Description

Technical Field

[0001] This utility model relates to the field of ball-throwing equipment, specifically to a ball-throwing machine. Background Technology

[0002] Balls have always been a favorite toy for children, and ball-throwing machines, as a type of amusement equipment that uses balls as a medium, are especially popular. Currently, most ball-throwing machines on the market have a fan installed inside, using the rapid airflow generated by the fan to launch the ball. For example, utility model patent "CN211676242U," entitled "Jet-type Ball Throwing Machine," discloses a jet-type ball-throwing machine, including a storage compartment, a ball inlet pipe, and a fan. One end of the ball inlet pipe is connected to the storage compartment, and the other end is open for the ball to enter. The fan provides airflow power from the open end to the storage compartment, and the fan is connected to the bottom of the storage compartment via a solenoid valve. When the solenoid valve is opened, the ball is ejected from the storage compartment. While this achieves the ball-throwing effect, because the ball is ejected from the top opening of the storage compartment, most of the ball is ejected vertically upwards, resulting in poor interactive throwing. Furthermore, since it relies solely on the fan's rotation speed to generate airflow, the throwing distance is relatively short. Summary of the Invention

[0003] To address the aforementioned shortcomings, the purpose of this utility model is to provide a ball-throwing machine with a reasonable structural design and good throwing effect.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A ball-throwing machine includes a housing, a V-shaped pipe, a dual-wheel ball-throwing device, and a triggering device. The V-shaped pipe is disposed on the housing, the dual-wheel ball-throwing device is located at the bend of the V-shaped pipe, and the triggering device is located at the ball-throwing end of the V-shaped pipe. When a soft ball contacts the dual-wheel ball-throwing device, the soft ball is squeezed into the gap between the two wheels under the high-speed rotation of the dual wheels. As the wheels continue to rotate, the soft ball is gradually compressed. When the compression reaches a certain degree, the soft ball is squeezed and rapidly pushed out, giving it an initial velocity and thus launching it.

[0006] As a preferred embodiment of this utility model, the dual-wheel ball extrusion device includes a base, an upper frame, two motors, and two friction wheels. The middle part of the base is fixed to the bottom outer wall of the V-shaped pipe. Each end of the base is symmetrically provided with a wheel cavity that matches the outer contour of the friction wheel. The two side walls of the V-shaped pipe are respectively provided with openings that communicate with the wheel cavities. The two ends of the upper frame are provided with cavity covers that match the wheel cavities. The cavity covers are provided with machine cavities for installing the motors. The motors are fixed in the machine cavities. The two friction wheels are respectively located in the two wheel cavities and are provided on the rotating shafts of the corresponding motors. The outer circumference of the two friction wheels extends into the V-shaped pipe through the openings. The two friction wheels are driven by the two motors to rotate at high speed in opposite directions, which can stably squeeze the soft ball into the gap and push it out, ensuring the continuity and stability of the projection.

[0007] As a preferred embodiment of this utility model, the outer circumferential surface of the friction wheel is provided with a plurality of protrusions arranged along its circumferential direction. The protrusions can increase the friction between the friction wheel and the soft ball, and can compress the soft ball more quickly, thereby enabling the soft ball to obtain a greater initial velocity and improving the projection distance.

[0008] As a preferred embodiment of this utility model, the triggering device includes an infrared transmitter and an infrared receiver, which are symmetrically arranged on both sides of the ball-squeezing end of the V-shaped pipe, enabling sensitive detection of the soft ball's entry and timely triggering of the dual-wheel ball-squeezing device for projection.

[0009] As a preferred embodiment of this utility model, the V-shaped pipe is bent at an angle of 80-110 degrees, so that both the ball-in and ball-out ends of the V-shaped pipe are tilted upwards, which facilitates ball placement and projection, and results in better projection.

[0010] As a preferred embodiment of this utility model, the housing includes a bottom shell and a body covering the bottom shell. The top surface of the body is provided with a conical funnel. The ball-in-the-hole end of the V-shaped pipe is connected to the bottom surface of the conical funnel. The conical funnel is designed to facilitate the throwing of soft balls. The ball-out end of the V-shaped pipe is located on the front of the body, which is convenient for observation and interactive ball throwing.

[0011] As a preferred embodiment of this utility model, the upper and lower shells of the shell packaging are spliced ​​together. The splicing line between the upper and lower shells is located at a height lower than the ball outlet end of the V-shaped pipe on the front side, and then gradually rises to extend to the back side, which facilitates assembly and production.

[0012] As a preferred embodiment of this utility model, the upper shell is provided with a ball-out pipe ring that is fitted with the ball-out end of the V-shaped pipe, so that the transition between the upper shell and the ball-out end is good and the stability of the ball throwing is improved.

[0013] As a preferred embodiment of this utility model, it also includes a delay device, which is disposed on the V-shaped pipe at a position below the triggering device. The delay device includes a delay rotating gear assembly and a ball-separating claw. The center position of the ball-separating claw is disposed on the delay shaft of the delay rotating gear assembly, and a slot is provided on the V-shaped pipe for the claw feet of the ball-separating claw to extend into it. This allows the soft balls to be separated in an orderly manner and slowly enter the position of the double-wheel ball extrusion device for throwing, avoiding chaotic and jammed phenomena.

[0014] The beneficial effects of this invention are as follows: The invention features a reasonable structural design. When the soft ball enters the V-shaped pipe, the triggering device can sensitively detect its entry and promptly trigger the high-speed rotation of the dual-wheel extrusion device. When the soft ball contacts the dual-wheel extrusion device, it is squeezed into the gap between the two wheels under the high-speed rotation of the wheels. As the wheels continue to rotate, the soft ball is gradually compressed. When compressed to a certain extent, the soft ball is rapidly pushed out, giving it an initial velocity and allowing it to be projected. Compared to traditional fan-assisted spraying, this method offers a longer projection distance, more controllable directional range, and better projection effect, greatly increasing player interest, providing high fun, strong entertainment, and good interactivity.

[0024] See the example. Figures 1 to 8 The ball-throwing machine provided in this embodiment includes a housing 1, a V-shaped pipe 2, a double-wheel ball-throwing device 3, a triggering device 4, a delay device 5, a power supply, and a control circuit board 6. The control circuit board 6 is connected to the double-wheel ball-throwing device 3, the triggering device 4, the delay device 5, and the power supply.

[0025] The V-shaped pipe 2 is disposed on the housing 1. The bending angle of the V-shaped pipe 2 is preferably 80-110 degrees, so that both the ball-infeeding end 201 and the ball-outfeeding end 202 of the V-shaped pipe 2 are inclined upwards, facilitating ball placement and throwing, and improving the throwing effect. Specifically, the housing 1 includes a bottom shell 11 and a body 12 covering the bottom shell 11. The top surface of the body 12 is provided with a conical funnel 13. The ball-infeeding end 201 of the V-shaped pipe 2 is connected to the bottom surface of the conical funnel 13. The design of the conical funnel 13 facilitates the placement of soft balls. The ball-outfeeding end 202 of the V-shaped pipe 2 is located on the front of the body 12, facilitating observation and interactive ball throwing. For ease of assembly and production, the body 12 contains a spliced ​​upper shell 121 and a lower shell 122. The splicing line between the upper shell 121 and the lower shell 122 is located at a height lower than the ball-outfeeding end 202 of the V-shaped pipe 2 on the front, and then gradually rises to extend to the back. The upper shell 121 is provided with a ball outlet ring 14 that is fitted to the ball outlet end 202 of the V-shaped pipe 2, so that the upper shell 121 and the ball outlet end 202 have a good transition effect and improve the stability of the ball throwing.

[0026] The dual-wheel ball extrusion device 3 is located at the bend of the V-shaped pipe 2. Specifically, the dual-wheel ball extrusion device 3 includes a base 31, an upper frame 32, two motors 33, and two friction wheels 34. The middle part of the base 31 is fixed to the bottom outer wall of the V-shaped pipe 2. Each end of the base 31 is symmetrically provided with a wheel cavity 311 that matches the outer contour of the friction wheel 34. The two side walls of the V-shaped pipe 2 are respectively provided with openings 21 that communicate with the wheel cavities 311. The two ends of the upper frame 32 are provided with cavity covers 321 that match the wheel cavities 311. The cavity covers 321 are provided with machine cavities 322 for installing the motors 33. The motors 33 are fixed in the machine cavities 322. The two friction wheels 34 are respectively located in the two wheel cavities 311 and are provided on the rotating shafts of the corresponding motors 33. The outer periphery of the two friction wheels 34 extends into the V-shaped pipe 2 through the openings 21. Two motors 33 drive two friction wheels 34 to rotate at high speed in opposite directions, which can stably squeeze the soft ball into the gap and push it out, ensuring the continuity and stability of the projection. Preferably, the outer circumferential surface of the friction wheel 34 is provided with a number of protrusions arranged in its circumferential direction. The protrusions can increase the friction between the friction wheel 34 and the soft ball, compress the soft ball more quickly, thereby enabling the soft ball to obtain a greater initial velocity and increasing the projection distance.

[0027] The triggering device 4 is located at the ball-pouring end 201 of the V-shaped pipe 2. In this embodiment, the triggering device 4 includes an infrared emitter 41 and an infrared receiver 42, which are symmetrically arranged on both sides of the ball-pouring end 201 of the V-shaped pipe 2. This allows for sensitive detection of the soft ball's entry and timely triggering of the dual-wheel ball-squeezing device 3 for projection. In other embodiments, the triggering device 4 can also be a photoelectric sensor or a tactile switch, etc.

[0028] The delay device 5 is positioned below the trigger device 4 on the V-shaped pipe 2. The delay device 5 includes a delay rotating gear assembly 51 and a ball-separating claw 52. The center of the ball-separating claw 52 is located on the delay shaft 517 of the delay rotating gear assembly 51. The V-shaped pipe 2 has slots into which the claw feet of the ball-separating claw 52 extend. The ball-separating claw 52 has four claw feet. (See also...) Figure 6 and Figure 7 The delayed rotary gear assembly 51 includes a gearbox 511 and a transmission pawl 512, a first gear 513, a second gear 514, a third gear 515, and a reduction gear plate 516 disposed within the gearbox 511. The transmission pawl 512 is fixed on the delayed rotating shaft 517. The first gear 513 is movably disposed on the delayed rotating shaft 517 and has a mating cavity 5131 on the surface facing the transmission pawl 512. The cavity wall of the mating cavity 5131 has ratchet teeth adapted to the transmission pawl 512. The first gear 513, the second gear 514, and the third gear 515 mesh sequentially. The reduction gear plate 516 is coaxially disposed with the second gear 514 and can swing freely. One end of the reduction gear plate 516 has a reduction pawl 5161 that can abut against the third gear 515 when it swings. One end of the reduction gear plate 516 has an elongated swing hole 5162 through which the delayed rotating shaft 517 passes. The ball-separating pawl 52 drives the transmission pawl 512 to rotate, which in turn drives the first gear 513 to rotate. The first gear 513, through the second gear 514, drives the third gear 515 to rotate. Because the delay-rotation gear set is inclined, the reduction gear plate 516 swings downwards under its own weight, causing the reduction pawl 5161 to contact the third gear 515. Simultaneously, the force on the reduction pawl 5161 causes the reduction gear plate 516 to swing rapidly, achieving rapid and repeated contact and separation between the reduction pawl 5161 and the third gear 515. This hinders the rotation of the third gear 515, achieving the purpose of deceleration and delay. This allows the soft balls to be orderly separated and slowly introduced into the position of the double-wheel ball-squeezing device 3 for ejection, avoiding chaotic jamming.

[0029] During play, a soft ball is placed in a conical funnel 13. Under the concentrated guidance of the conical funnel 13, the soft ball enters the ball-collecting end 201 of the V-shaped pipe 2 one by one. The triggering device 4 detects the entry of the soft ball and sends feedback to the control circuit board 6. The control circuit board 6 then promptly triggers the double-wheel ball-squeezing device 3 to rotate at high speed. Next, under the deceleration effect of the delay device 5, the soft ball enters the position of the double-wheel ball-squeezing device in an orderly manner and contacts the double-wheel ball-squeezing device 3. Driven by the high-speed rotation of the friction wheels 34 of the double-wheel ball-squeezing device 3, the soft ball is squeezed into the gap between them. As the two friction wheels 34 continue to rotate, the soft ball is gradually compressed. When compressed to a certain extent, the soft ball is squeezed and quickly pushed out, giving it an initial velocity for projection. This results in a longer projection distance and better projection effect. Furthermore, the machine casing 1 can be rotated to adjust the orientation of the ball end 202, making the throwing direction controllable. This greatly increases the player's interest, making it highly entertaining and interactive.
