The control module is arranged in the machine base 100 and is electrically connected with the reader 140, the stirring assembly 200 and the ball return assembly 300.

[0036] When drawing the prize, the stirring assembly 200 stirs the prize ball in the prize ball box 110, when the prize ball enters the ball outlet channel structure 120 through the ball outlet 111, the prize ball information can be read by the reader 140, when the prize ball is not damaged, the ball receiving disc 310 moves to the ball receiving position, the supporting part 311 receives the prize ball, then the ball receiving disc 310 drives the prize ball to move to the ball return position, the prize ball is sent into the ball return channel structure 130 by the ball return device 330, and returns to the prize ball box 110;When the prize ball is damaged, the ball receiving disc 310 moves to the ball discarding position, so that the damaged prize ball cannot enter the supporting part 311 of the ball receiving disc 310 and is discarded, then the ball supplementing structure 400 puts the standby prize ball into the supporting part 311, and then the ball receiving disc 310 moves to the ball return position, and the standby prize ball is sent back to the prize ball box 110 through the ball return channel structure 130;The above structure can automatically replace the damaged prize ball, reduces manual intervention, the way of replacing the damaged prize ball is relatively simple, reduces the maintenance difficulty, and is conducive to realizing automatic circulation drawing.

[0037] In the embodiment, the ball supplementing structure 400 is to put the standby prize ball into the ball receiving disc 310, and then the ball receiving disc 310 sends the standby prize ball into the prize ball box 110 through the ball returning device 330. It can be understood that in other embodiments, the ball supplementing structure 400 can also be open to communicate with the prize ball box 110, that is, the ball supplementing structure 400 directly puts the standby prize ball into the prize ball box 110.

[0038] Specifically, the prize ball is built-in with a readable chip, which records prize ball information. When the prize ball passes through the reader 140, the reader 140 can obtain the relevant information of the prize ball to determine whether the prize ball wins the prize.

[0039] In the embodiment, the ball receiving disc 310 can move to a ball supplementing position, and in the ball supplementing position, the supporting part 311 is opposite to the outlet of the ball supplementing structure 400. By moving the ball receiving disc 310 to the ball supplementing position, the ball supplementing structure 400 directly puts the standby prize ball into the supporting part 311 of the ball receiving disc 310 at this time, and then the ball receiving disc 310 moves to the ball returning position, and the standby prize ball is sent into the ball returning channel structure 130 through the ball returning device 330, so as to finally put the new prize ball into the prize ball box 110, which utilizes the original structure and function of the ball returning assembly 300, does not need to additionally increase many structures, obviously simplifies the way of replacing the damaged prize ball, and reduces the production cost.

[0040] In the embodiment, the ball supplementing structure 400 is a ball supplementing pipe, which is vertically arranged above the ball receiving disc 310, and the lower end of the ball supplementing pipe forms the outlet of the ball supplementing structure 400. The prize ball is in the ball supplementing pipe, and when the supporting part 311 of the ball receiving disc 310 is aligned with the lower end outlet of the ball supplementing pipe, the prize ball can fall into the supporting part 311 of the ball receiving disc 310 by its own gravity, so that the implementation of the ball supplementing structure 400 is relatively simple and reliable.

[0041] In the embodiment, the ball receiving disc 310 is provided with a stop part 312, which stops the outlet of the ball supplementing structure 400 in the ball receiving position, the ball returning position and the ball discarding position, and avoids the outlet of the ball supplementing structure 400 in the ball supplementing position. The ball receiving disc 310 is provided with the stop part 312, which can avoid the risk of the standby prize ball of the ball supplementing structure 400 flowing out when the ball supplementing is not needed, so that the ball receiving disc 310 also has the function of the gate of the ball supplementing structure 400 through the stop part 312, so that the structure of the lottery machine is compact, and the equipment manufacturing cost is reduced. When the ball receiving disc 310 is in the ball supplementing position, the stop part 312 avoids the outlet of the ball supplementing structure 400, so that the standby prize ball in the ball supplementing structure 400 can enter the supporting part 311 of the ball receiving disc 310.

[0042] Specifically, the stop portion 312 is a plate body, and the stop portion 312 of the ball receiving disc 310 can block the outlet of the ball supplementing structure 400, so as to avoid the accidental ball supplementing of the ball supplementing structure 400. It can be understood that the stop portion 312 can also be a block body or the like.

[0043] It can be imagined that in other embodiments, the ball supplementing structure 400 can also be a ball storage box and a mechanical hand, the ball storage box is provided with spare prize balls, and the spare prize balls are placed into the prize ball box 110 or the supporting portion 311 of the ball receiving disc 310 by the mechanical hand to achieve the placement of the spare prize balls; or the ball supplementing structure 400 includes a ball storage funnel and a valve, the valve is located at the lower end opening of the ball storage funnel, and the lower end opening of the ball storage funnel is located at the side wall of the prize ball box 110. When the ball needs to be supplemented, the valve can be opened, so that the spare prize balls in the ball storage funnel fall into the prize ball box 110.

[0044] Specifically, in some embodiments, the ball supplementing pipe can store some spare prize balls for a long time, so as to replace the prize balls at any time. Or the ball supplementing pipe can also be extended to the outside of the machine base, and the maintenance personnel manually add the supplementary prize balls.

[0045] In embodiments, the ball receiving disc 310 is rotationally arranged on the machine base 100, and the rotation axis is arranged along the up-down direction. The ball receiving disc driver 320 is used to drive the ball receiving disc 310 to rotate. The outlet of the ball outlet channel structure 120, the inlet of the ball return channel structure 130 and the outlet of the ball supplementing structure 400 are arranged around the rotation axis of the ball receiving disc 310, and the ball receiving disc 310 is located below the outlet of the ball outlet channel structure 120, the inlet of the ball return channel structure 130 and the outlet of the ball supplementing structure 400. The ball receiving disc 310 switches the ball receiving position, the ball returning position, the ball discarding position and the ball supplementing position by rotation, and the movement mode is relatively simple, so that the arrangement of the ball outlet channel structure 120, the ball return channel structure 130 and the ball supplementing structure 400 can be relatively compact, which is beneficial to the miniaturization trend of the equipment and the reduction of the cost of the equipment.

[0046] Specifically, the ball receiving disc driver 320 can adopt a rotation driver 220 such as a motor to drive the ball receiving disc 310 to rotate. It can be imagined that in other embodiments, the ball receiving disc driver 320 can also be other structures capable of outputting rotation power such as a rotary air cylinder, and the person skilled in the art can select it according to actual needs.

[0047] In embodiments, the ball receiving disc 310 is provided with an avoiding hole 313, and the avoiding hole 313 is arranged along the vertical direction. In the ball discarding position, the avoiding hole 313 is located below the outlet of the ball outlet channel structure 120. The avoiding hole 313 is arranged, and the damaged prize ball can leave the ball receiving disc 310 through the avoiding hole 313 and enter other positions of the machine base 100 when leaving the ball outlet channel structure 120.

[0048] Specifically, the collecting basket 600 is arranged in the base 100 and located below the avoiding hole 313. When the damaged prize ball passes through the avoiding hole 313, the damaged prize ball enters the collecting basket 600 for unified collection, thereby facilitating recycling.

[0049] It is conceivable that, in other embodiments, the ball receiving disc 310 can also be linearly movable and arranged in the base 100. At this time, the ball disc driver 320 can adopt a structure outputting linear power such as a pneumatic cylinder or an electric cylinder. The ball receiving disc 310 switches the ball receiving position, the ball returning position, the ball abandoning position and the ball supplementing position through linear movement.

[0050] Specifically, the ball receiving disc 310 of the present scheme has the same ball returning position and ball abandoning position. That is, when the supporting part 311 is aligned with the opening of the ball returning channel structure 130, the avoiding hole 313 is also aligned with the opening of the ball outlet channel structure 120, thereby simplifying the operation process of the ball receiving disc 310 and reducing the design and use difficulty.

[0051] It is conceivable that, in some embodiments, when the ball receiving disc 310 is in the ball abandoning position, the damaged prize ball can also directly fall into other positions in the base after passing through the avoiding hole 313. Those skilled in the art can make specific selection according to actual needs.

[0052] In an embodiment, the supporting part 311 is a concave hole, the bottom of the concave hole is hollowed out, the ball returning device 330 is a fan, and in the ball returning position, the air outlet of the fan is opposite to the entrance of the ball returning channel structure 130, and the supporting part 311 is located between the air outlet of the fan and the entrance of the ball returning channel structure 130. When the ball receiving disc 310 is in the ball returning position, the fan blows air flow through the air outlet, the air flow passes through the meshed bottom of the concave hole and pushes the prize ball into the ball returning channel structure 130, and finally the prize ball enters the prize ball box 110. The prize ball is driven to return by the fan, and the structure is simple and easy to implement.

[0053] It is conceivable that, in other embodiments, the ball returning device 330 can also be an electric push rod. At this time, the supporting part 311 is provided with a small hole, the electric push rod passes through the small hole and directly pushes the prize ball into the ball returning channel structure 130, and finally returns to the prize ball box 110. At this time, the ball returning channel structure 130 is preferably a straight pipe body. Alternatively, the supporting part 311 is a plate body, and the ball returning device 330 adopts a mechanical hand. At this time, the ball returning channel structure 130 is preferably located above the prize ball box 110. The prize ball on the ball receiving disc 310 is grabbed by the mechanical hand and placed into the ball returning channel structure 130, so that the prize ball returns to the prize ball box 110 under the action of gravity.

[0054] In the embodiment, the ball outlet 111 is located at the lower side of the prize ball box 110, the base 100 is provided with a selection disc 510 and a selection driver 520, the selection disc 510 is rotationally arranged on the base 100 and the rotation axis is arranged in the horizontal direction, the selection disc 510 is located below the ball outlet 111 and in the ball outlet passage structure 120, the ball outlet 111 is opposite to the outer circumferential side of the selection disc 510, the outer circumferential side of the selection disc 510 can stop the ball outlet 111, and the outer circumferential side of the selection disc 510 is provided with a prize ball accommodating groove 511, and the selection driver 520 drives the selection disc 510 to rotate.

[0055] In the normal state, the outer circumferential side of the selection disc 510 is opposite to the ball outlet 111 and blocks the prize ball in the prize ball box 110 from entering the ball outlet passage structure 120 through the ball outlet 111. When the lottery machine draws a prize, the selection driver 520 drives the selection disc 510 to rotate, when the prize ball accommodating groove 511 of the selection disc 510 is aligned with the ball outlet 111, the prize ball in the prize ball box 110 can pass through the ball outlet 111 into the prize ball accommodating groove 511 under the action of gravity, and then the remaining prize balls can no longer pass through the ball outlet 111; the selection disc 510 continues to rotate to re-block the ball outlet 111. When the selection disc 510 rotates to the slot downward, the prize ball leaves the selection disc 510 under the action of gravity and continues to move along the ball outlet passage structure 120, so that the prize ball finally enters the ball receiving disc 310.

[0056] Specifically, the reader 140 is located beside the selection disc 510, and the reader 140 can read the information of the prize ball when the prize ball passes through the reader 140 under the action of the selection disc 510. The rotation speed of the selection disc 510 can be adjusted to a relatively appropriate speed to avoid the risk that the prize ball passes through the reader 140 too fast and the reader 140 cannot read the information of the prize ball.

[0057] In the embodiment, the ball outlet passage structure 120 and the ball return passage structure 130 are arranged in the up-down direction, and the ball outlet passage structure 120 is located at the lower side of the prize ball box 110. It can be understood that in other embodiments, the ball outlet passage structure 120 and the ball return passage structure 130 can also be arranged in other ways, which can be specifically selected by those skilled in the art according to actual needs.

[0058] Specifically, the ball outlet passage structure 120 is approximately funnel-shaped, that is, the cross-sectional area of the ball outlet passage structure 120 gradually decreases in the direction from top to bottom, which facilitates accommodating the selection disc 510.

[0059] In the embodiment, the stirring assembly 200 comprises a stirring frame 210 and a rotating driver 220, the stirring frame 210 is pivoted to the base 100 and the rotating axis is arranged in the horizontal direction, and the rotating driver 220 is used to drive the stirring frame 210 to rotate. The rotating driver 220 drives the stirring frame 210 to rotate to stir the prize balls in the prize ball box 110, the structure is relatively simple, and the stirring effect of the prize balls is relatively uniform.

[0060] Specifically, the rotating driver 220 adopts a speed reducer motor. It can be imagined that, in other embodiments, the rotating driver 220 can also be a structure that outputs rotating power, such as a rotary cylinder, and the person skilled in the art can select it according to actual needs.

[0061] In the embodiment, the ball outlet 111 is located on the lower side wall of the prize ball box 110, the ball return port 112 is located on the rear side wall of the prize ball box 110, the stirring frame 210 comprises a rotating shaft 211, three stirring rods 212 and three elastic members 213, the output shaft of the rotating driver 220 is connected with the rotating shaft 211, one end of the stirring rod 212 is connected with the rotating shaft 211, the elastic member 213 is arranged in the front-rear direction, the front end of the elastic member 213 is connected with the other end of the stirring rod 212 one by one, and the other end of the stirring rod 212 is located on the front side of the ball outlet 111.

[0062] Specifically, the other end of the stirring rod 212 is staggered with the ball outlet 111 and the ball return port 112 in the front-rear direction, when the stirring frame 210 rotates, the hard stirring rod 212 can avoid directly hitting the prize balls near the ball outlet 111 and the ball return port 112, and mainly use the elastic member 213 to impact the prize balls near the ball outlet 111 and the ball return port 112, so as to reduce the risk of damage of the prize balls and improve the service life of the prize balls.

[0063] Specifically, the stirring rod 212 is sequentially connected by the internal segment 2121, the middle segment 2122 and the external segment 2123 through bending, and the external end is located on the front side of the internal segment 2121, so that the middle segment 2122 can hit the prize balls that are stirred and accumulated at a high position, and the overall stirring effect is good.

[0064] Specifically, the elastic member 213 is a rubber band ring, and the other end of the stirring rod 212 is fixed to the front end of the rubber band ring. It can be imagined that, in other embodiments, the elastic member 213 can also be an elastic plate, an elastic strip, etc., and the material can be, for example, silica gel, rubber or other elastic plastic, and the person skilled in the art can select it according to actual needs.

[0065] It can be imagined that in other embodiments, the stirring assembly 200 can also be other structures, for example, the stirring assembly 200 comprises an air pump, the air outlet of the air pump is communicated with the prize ball box 110, and the air pump blows high-pressure air flow into the prize ball box when the air pump is started. The air flow can push the prize balls in the prize ball box 110 to move, so as to also be able to stir the prize balls in the prize ball box 110.

[0066] Specifically, the front side of the machine base 100 is also provided with a card swiping device 150 and a button 160. When the user plays, after swiping the card through the card swiping device 150, the lottery machine starts the lottery, and then the user can tap the button 160.
