Description

Technical Field

[0001] This utility model belongs to the field of lottery machine technology, specifically relating to an automatic lottery machine. Background Technology

[0002] In existing amusement venues such as amusement parks, arcades, and children's playgrounds, owners often use lucky draws to liven up the atmosphere. The traditional method involves customers drawing balls from an opaque box. The prize is determined by comparing the printed number on the ball with the announced prizes. After the prize is awarded, staff decide whether to return the ball to the box or remove it without returning it, depending on the game's rules. This entire process is done manually, leading to the following problems: 1. Oversights can result in incorrect prizes or failure to follow the rules for returning or removing balls; 2. Cheating can occur, with staff awarding grand prizes to specific customers out of personal bias; 3. The more draws there are, the more time is required for number announcements and prize redemption, reducing overall efficiency. All these problems ultimately result in economic losses for the store or a negative customer experience. Therefore, automatic lottery machines are gradually being adopted by existing amusement venues such as amusement parks, arcades, and children's playgrounds. However, although a small number of existing automatic lottery machines have the function of actively recognizing lottery ball information, most of them can only perform the lottery action according to a single rule. That is, they cannot choose to put the lottery ball back into the prize pool to participate in the subsequent lottery, or to remove it from the prize pool and not participate in the subsequent lottery.

[0003] To address the aforementioned phenomena and problems, this paper presents an automatic lottery machine that features both automatic identification capabilities, allowing for the automatic recognition of the winning numbers of the drawn lottery balls, and the ability to set lottery rules, selecting and executing specific rules based on game settings. This solution strictly adheres to the set lottery rules, completely eliminating errors and cheating caused by human intervention, improving the efficiency and fairness of the lottery process, and ensuring the impartiality of the lottery results.

Detailed Implementation

[0021] To provide a more detailed description of this utility model, the following description is provided in conjunction with the accompanying drawings. It should be noted that the embodiments described below are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0022] See Figure 1 This embodiment provides an automatic lottery machine for automatically identifying and sorting lottery results, including a ball mixing pool 1, an identification and sorting structure 2, a ball receiving structure, and a microcontroller component.

[0023] The mixing pool 1 is equipped with a stirring component and several lottery balls 13. The stirring component includes a stirring shaft 11 fixed at the center of the mixing pool 1 and multiple stirring rods 12 radiating outward from the stirring shaft 11. The stirring rods 12 rotate clockwise around the stirring shaft 11 to stir and scramble the lottery balls 13 in the mixing pool 1, causing the lottery balls 13 to randomly fall into the identification and sorting structure 2. The lottery balls 13 are equipped with RFID tags with specific numbers inside, and the outer surface is printed with the corresponding numbers carried by the RFID tags inside.

[0024] See Figure 2 and Figure 3 The identification and sorting structure 2 is used to read the number of the drawn lottery ball 13 and determine the taking out and putting back of the lottery ball 13 according to the lottery rules set for a specific game. It is set below the ball mixing pool 1 and specifically includes a sorting shell 21, a sorting turntable 22, a steering component and an identification component.

[0025] The sorting housing 21 is vertically disposed below the mixing pool 1, and its interior is a hollow cavity. A sorting inlet 216 is provided at the top, and a first ball outlet 217 and a second ball outlet 218 are arranged side-by-side at the bottom. The sorting inlet 216 is connected to the lower part of the mixing pool 1. In this embodiment, the sorting housing 21 consists of a front sorting housing 211 and a rear sorting housing 213. The front sorting housing 211 and the rear sorting housing 213 are symmetrically provided with mounting blocks 215 on their sides. The front sorting housing 211 and the rear sorting housing 213 can be connected by a snap-fit ​​or threaded structure on the mounting blocks 215. The sorting shell 213 is fixed after sorting; the sorting inlet 216 is located on the top of the sorting front shell 211; the first ball outlet 217 is used to output the lottery ball 13 that needs to be returned to the mixing pool 1; the second ball outlet 218 is used to output the lottery ball 13 that needs to be taken away; a display groove 212 can also be provided on the sorting front shell 211, the width of the display groove 212 is smaller than the diameter of the lottery ball 13, so as to display the lottery ball 13 that has been drawn; specifically, a limiting piece 214 is provided on the sorting rear shell 213 corresponding to the transfer platform 225.

[0026] See Figure 3 and Figure 4 The sorting turntable 22 is rotatably disposed within the sorting housing 21, and includes an upper turntable 221, a lower rotating block 223, and a rotating shaft 23. The upper turntable 221 is provided with a ball-collecting port 222, and the lower rotating block 223 is provided with an identification slide 224 symmetrically positioned with respect to the ball-collecting port 222. The upper turntable 221 and the lower rotating block 223 are connected and fixed together by the rotating shaft 23, and a transfer platform 225 is disposed between them. The top of the rotating shaft 23 is rotatably disposed at the top center of the sorting housing 21. In this embodiment, the width of the transfer platform 225 and the identification slide 224 is slightly larger than the diameter of the lottery ball 13, which ensures that only one lottery ball 13 falls into the sorting turntable 22 each time and is successfully identified and sorted in the subsequent process.

[0027] The steering assembly is located at the lower end of the rotating shaft 23 and includes a drive motor 31 located at the center of the bottom of the sorting front shell 211 and a reversing gear 32 connected between the drive motor 31 and the rotating shaft 23. It is used to transmit the motor torque to the sorting turntable 22 to drive the sorting turntable 22 to rotate.

[0028] The identification component is located at the bottom of the lower rotating block 223 and includes an RFID reading circuit board 41 and an RFID reading antenna 42. The RFID reading circuit board 41 is used to read the RFID tag in the lottery ball 13 located in the identification slide 224 in real time, and the RFID reading antenna 42 is used to transmit the reading result to the microcontroller component.

[0029] The ball-collecting structure is used to return the lottery ball 13 to the mixing pool 1 according to the lottery rules of a specific game. It is located between the mixing pool 1 and the first ball outlet 217, and includes a ball-loading channel 51 and a blower. The upper section of the ball-loading channel 51 extends into the mixing pool 1, and its top end is provided with a ball-collecting outlet 52. Its lower section is provided with a ball-collecting inlet 53, and its tail end is provided with an air inlet 54. The ball-collecting inlet 53 is connected to the first ball outlet 217. The air outlet of the blower is connected to the air inlet 54, and is used to input high-speed gas to send the lottery ball 13 back to the mixing pool 1 through the ball-loading channel 51.

[0030] The microcontroller component is communicatively connected to the identification component, the driving component, and the stirring component, respectively, and is used to receive the lottery identification results in real time, select the outlet of the lottery ball 13, and adjust the mixing state of the lottery balls 13 in the mixing pool 1. In this embodiment, the microcontroller component can also be equipped with a display screen or a player to promptly display the winning numbers.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the automatic lottery machine is used in the following steps:

[0032] Step 1: The microcontroller program pre-sets the lottery rules for this game, that is, whether the lottery ball 13 drawn is put back into the mixing ball pool 1 to participate in the subsequent lottery, or taken away and no longer participating in the subsequent lottery.

[0033] Step 2: The sorting turntable 22 is in the reset state 61, that is, the ball-collecting port 222 on the upper turntable 221 faces the sorting rear shell 213, and the identification slide 224 on the lower turntable 223 faces the sorting front shell 211. At this time, the upper turntable 221 completely blocks the sorting entrance 216; the stirring rod 12 continuously stirs the lottery balls 13 in the mixing pool 1, and multiple lottery balls 13 move randomly in the mixing pool 1;

[0034] Step 3: The steering component drives the rotating shaft 23 to rotate, thereby causing the sorting turntable 22 to rotate 180 degrees to enter the lottery state 62, so that the ball picking port 222 coincides with the sorting inlet 216, and the identification slide 224 faces the sorting back shell 213, so that a lottery ball 13 falls into the transfer platform 225 and becomes the lottery ball 13 drawn.

[0035] Step 4: When the transfer platform 225 has the drawn lottery ball 13, the steering component drives the rotating shaft 23 to rotate again, so that the sorting turntable 22 enters the reset state 61 again. At this time, the drawn lottery ball 13 falls from the transfer platform 225 into the identification slide 224.

[0036] Step 5: Activate the RFID reading circuit board 41 to read the RFID tag inside the lottery ball 13 to obtain the winning number, and transmit the reading result to the microcontroller component through the RFID reading antenna 42.

[0037] Step Six: According to the pre-set lottery rules, if the set lottery rules are that the drawn lottery ball 13 is returned to the mixing pool 1 to participate in the subsequent lottery, then the steering component drives the rotating shaft 23 to rotate clockwise, so as to drive the sorting turntable 22 to rotate 90 degrees clockwise and enter the first lottery state 63. At this time, the identification slide 224 is connected to the first ball outlet 217, and the drawn lottery ball 13 falls into the ball loading channel 51 through the first ball outlet 217. The blower inputs high-speed gas to send the drawn lottery ball 13 back to the mixing pool 1.

[0038] Step 7: According to the pre-set lottery rules, if the lottery ball 13 is taken away and will not participate in the subsequent lottery, the steering component drives the rotating shaft 23 to rotate counterclockwise, thereby driving the sorting turntable 22 to rotate counterclockwise by 90 degrees and enter the second prize-giving state 64. At this time, the identification slide 224 is connected to the second ball outlet 218, and the lottery ball 13 falls into the second ball outlet 218 and is no longer put back into the mixing pool 1.

[0039] In this embodiment, the above is merely an example and is not intended to limit the scope of protection of this application.

[0040] This utility model provides an automatic lottery machine. Each lottery ball in the mixing pool is internally equipped with an RFID tag bearing a specific number. Below the mixing pool is an identification and sorting structure consisting of a sorting shell, a sorting turntable, a steering assembly, and an identification assembly. The sorting turntable is a double-layered structure consisting of an upper turntable and a lower rotating block.
