[0030] The embodiments of the present application are described below in combination with Figures 1 to 8 The embodiments of the present application are described below in combination with

[0031] The present embodiment relates to a number selecting machine, referring to Figure 1 and Figure 3 which comprises a base 100, a rotating disc 400, a ball guide cover 200, a number selecting disc 300 and a driving device (not shown in the figure).

[0032] The rotating disc 400 is installed in the base 100, and the guide ball cover 200 is arranged outside the rotating disc 400; the number selecting disc 300 is arranged in the guide ball cover 200, and a plurality of accommodating grooves 340 are arranged on the number selecting disc 300; optionally, a plurality of convex strips are arranged on the upper surface of the rotating disc 400, and the plurality of convex strips are arranged at intervals along the circumferential direction of the surface of the rotating disc 400; when the rotating disc 400 rotates, the originally relatively smooth rolling path of the number balls is interrupted by the convex strips, so that the number balls change direction and speed, and irregular movements such as jumping are generated, thereby promoting the collision between the number balls and the collision between the number balls and the edge of the rotating disc 400 to be more frequent.

[0033] The driving device is arranged in the base 100 and is used to drive the rotating disc 400 to rotate. Optionally, the driving device comprises a motor, the motor is arranged below the rotating disc 400, the output shaft of the motor is connected with the rotating shaft of the rotating disc 400, the rotating disc 400 is driven to rotate by the motor, further, a battery groove is arranged on the base 100, a battery is installed in the battery groove, and the battery is electrically connected with the motor, at the same time, a power button 120 is arranged on the base 100, and the battery is electrically connected with the power button 120, so that only the power button 120 needs to be pressed when in use, and the rotating disc 400 can start to rotate to draw numbers. A lithium battery can also be arranged on the base 100, a charging interface is arranged on one side of the base 100, the lithium battery is electrically connected with the motor, and the lithium battery can be used after being charged by an external charger, so that the battery does not need to be frequently replaced, and the use is more convenient.

[0034] The driving device is arranged in the base 100 and is used to drive the rotating disc 400 to rotate. Optionally, the driving device comprises a motor, the motor is arranged below the rotating disc 400, the output shaft of the motor is connected with the rotating shaft of the rotating disc 400, the rotating disc 400 is driven to rotate by the motor, further, a battery groove is arranged on the base 100, a battery is installed in the battery groove, and the battery is electrically connected with the motor, at the same time, a power button 120 is arranged on the base 100, and the battery is electrically connected with the power button 120, so that only the power button 120 needs to be pressed when in use, and the rotating disc 400 can start to rotate to draw numbers. A lithium battery can also be arranged on the base 100, a charging interface is arranged on one side of the base 100, the lithium battery is electrically connected with the motor, and the lithium battery can be used after being charged by an external charger, so that the battery does not need to be frequently replaced, and the use is more convenient.

[0035] Exemplarily, when in use, the number balls are placed on the rotating disc 400, the guide ball cover 200 is covered, the power button 120 on the base 100 is pressed, the motor is started and drives the rotating disc 400 to rotate, so that the number balls roll and jump in the space of the guide ball cover 200, the number balls after jumping fall into the accommodating grooves 340 of the number selecting disc 300. When a preset number of number balls fall, the button 120 is stopped, the motor stops working, and the number balls stop moving. At this time, the number of the number balls falling into the accommodating grooves 340 can be read through the guide ball cover 200, and one round of drawing numbers is completed. Subsequently, the entire number selecting device is reversed and inverted, so that all the number balls fall into the ball cover, and then the number selecting device is slowly reversed, so that the number balls slide back to the rotating disc 400 along the inner wall of the guide ball cover 200, and the second round of drawing numbers can be started, which is convenient and fast.

[0036] In some embodiments, referring to Figure 5A structural schematic diagram of a selection dial 300 is shown, the selection dial 300 comprises a supporting part 310, a baffle 330 and a supporting part 320, the supporting part 310 is connected with the supporting part 320, the supporting part 320 is connected with the base 100, the baffle 330 is multiple, and the multiple baffles 330 are arranged on the supporting part 310 and enclosed to form multiple accommodating grooves 340. In the drawing activity, referring to Figure 4 Each accommodating groove 340 can accommodate a number ball, so that each accommodating groove 340 corresponds to only one specific number or prize, and then the corresponding number or prize can be determined.

[0037] Generally, when shaking the number, the shaking number condition is generally observed from the side of the shaking number machine, and thus, in some embodiments, the supporting part 310 is arranged close to the inner wall of the guide ball cover 200, and the accommodating groove 340 is provided with an opening towards the side of the guide ball cover 200. The selection dial 300 is arranged close to the inner wall of the guide ball cover 200, and the opening of the accommodating groove 340 is arranged towards the side of the guide ball cover 200, so that the falling condition of the ball can be observed relatively easily, and at the same time, the opening of the accommodating groove 340 is arranged towards the side of the guide ball cover 200, which reduces the shielding of the number ball reading by other components, so that the shaking number result can be observed more intuitively.

[0038] In use, the number selector may be subjected to external force, such as collision when the number ball moves, slight vibration of the base 100, etc., and thus, in some embodiments, the base 100 is provided with a slot 610 corresponding to the bottom of the supporting part 320, and the supporting part 320 is inserted and fixed in the slot 610. In the process of frequent shaking number operation, the number selector needs to withstand the repeated impact and rolling force generated by the number ball, and by providing the slot 610, after the supporting part 320 is inserted into the slot 610 of the base 100, a stable structure can be formed, the upright state of the number selector is maintained, and the stability of the selection dial 300 in the shaking number process is ensured. More advantageously, the slot 610 can serve as a positioning point to provide an accurate installation position for the supporting part 320, so that the installation process of the selection dial 300 is more convenient.

[0039] Further, the base 100 is provided with a fixing ring 600, and the slot 610 is arranged on the fixing ring 600. Thus, by arranging the slot 610 on the fixing ring 600, the shaking number machine can be conveniently disassembled and fixed, and when installed, the supporting part 320 is inserted into the slot 610 for fixation, which effectively reduces the loosening or damage of the components caused by the movement impact of the number ball, and improves the stability and durability of the shaking number machine. Even in the case of long-term use or under the condition of large vibration, the connection of the internal components can be ensured to be firm.

[0040] When the number shaker is used in a lottery activity with number balls of multiple colors or different prize levels, in some embodiments, the number shaker is further provided with a partition plate 500, one side of the partition plate 500 is provided with a splicing interface 530, the partition plate 500 is connected with the number selection disc 300 through the splicing interface 530, and the partition plate 500 can divide the number selection disc 300 into two number areas. For example, the accommodating groove 340 on the left side of the partition plate 500 is a common number area, and the accommodating groove 340 on the right side is a special number area. The space in the ball guide cover 200 can also be divided into different areas. For example, in a lottery activity with number balls of special prize and common prize, the number shaker is divided into two areas by the partition plate 500, and number balls of corresponding prize levels or colors are placed in each area. In this way, during the shaking process, shaking can be performed on different areas at the same time. In this way, different types of shaking objects can be clearly distinguished. In order to further increase the stability of the partition plate 500, the fixing ring 600 is further provided with a fixing groove 630 corresponding to the shape of the bottom of the partition plate 500, and the bottom of the partition plate 500 is inserted into the fixing groove 630.

[0041] When the number shaker is used in different activities, the rules of the number lottery may be different, and in the related number shaking technical solution, only one set of numbers can be selected, and the accommodating groove 340 of the number shaker cannot be adjusted correspondingly according to the rules. Therefore, in some embodiments, referring to Figure 3 and Figure 4 , one side of the number selection disc 300 is provided with a plurality of splicing grooves 350 corresponding to the baffle 330, and the splicing interface 530 and the splicing groove 350 are matched. Therefore, not only is the disassembly of the partition plate 500 convenient, but also the adjustment of the position of the partition plate 500 can be realized, so that the position of the partition plate 500 can be changed according to the actual situation, thereby changing the number of accommodating grooves of the two number areas.

[0042] After connecting the partition plate 500 and the number selection disc 300, in order to facilitate group shaking, referring to Figure 8 , the partition plate 500 can be provided as a closed partition plate 520, the middle part of which is a fully closed structure, and double-warehouse simultaneous shaking can be realized. For example, in a number shaking activity including different prize levels or different categories, different types or different colors of balls can be placed on both sides of the partition plate, so that they do not interfere with each other during the shaking process, and group simultaneous shaking is realized.

[0043] In some number shaking scenarios that require mixing of different types of balls, referring to Figure 7, the partition plate 500 can be provided as a hollow partition plate 510 with a through structure in the middle. For example, in the number selection of a multi-color ball lottery, by providing a through structure, multiple color balls such as red balls and blue balls can be fully mixed on the rotating disc 400. When shaking the numbers, the number ball can temporarily enter one side of the hollow partition plate 510 under strong vibration or impact of other balls, and then return to the bottom of the rotating disc 400, and then jump into the other side of the hollow partition plate 510 or smoothly fall into the containing groove 340. In this way, each ball has more opportunities to mix with other balls during the shaking process, so that the residence time, rolling direction and timing of rolling back into the rotating disc 400 from one side are full of uncertainty, so that each number ball has a probability of being shaken out, effectively avoiding shaking probability deviation caused by design defects, thereby increasing the randomness of shaking.

[0044] In some embodiments, the base 100 is provided with a boss 110 at the top, the guide ball cover 200 is covered outside the boss 110, the boss 110 is provided with a mounting position, and the rotating disc 400 is mounted in the mounting position. The rotating disc 400 is installed in the mounting position, and the boss 110 provides a placement platform for the rotating disc 400 and the number ball, and can also concentrate the number ball to a specific area on the rotating disc 400, preventing the number ball from scattering.

[0045] In some embodiments, the inner wall of the boss 110 is provided with an inclined surface 620, which is inclined in the direction of the rotating disc 400, so that the inner wall of the boss 110 presents a horn-shaped structure with a wide top and a narrow bottom, which is beneficial to reduce the gap between the inclined surface 620 and the rotating disc 400, prevent the number ball from being stuck in the gap when rolling, and ensure the continuity and smoothness of shaking.

[0046] In some embodiments, the boss 110 is provided with a groove 150, and the guide ball cover 200 is inserted in the groove 150. During the shaking process, the number ball always moves inside the guide ball cover 200. By inserting the guide ball cover 200 into the groove 140, the position of the guide ball cover 200 can be stabilized to prevent displacement of the guide ball cover 200 when shaking or being hit by the number ball. Further, the outer wall of the guide ball cover 200 is provided with a buckle 210, and one side of the groove 150 is provided with a buckle opening matched with the buckle 210. The buckle 210 is matched with the buckle opening, and after matching, the guide ball cover 200 is rotated to lock the buckle 210, thereby tightly fixing the guide ball cover 200 on the base 100, avoiding the guide ball cover 200 from being separated from the base 100 during shaking.

[0047] In order to facilitate observation of the number drawing process, in some embodiments, the guide ball cover 200, the number selection disc 300, and the separation plate 500 are made of transparent material. For the operator and the audience, since the number balls are distributed in the rotating disc 400 and are not blocked by other structures during the number drawing, the movement of each number ball can be clearly observed. For example, in a commercial promotion lottery activity, the customer can directly observe the rolling of the number ball corresponding to the prize he or she is interested in, thereby increasing the transparency of the lottery process. Alternatively, the grid in the number selection disc 300 or the separation plate 500 can be specially designed, such as setting different color grids to represent different prize levels, or adding decorations on the number selection disc 300 or the separation plate 500. When the ball falls into these grids with visual effects, visual attraction is generated, making the entire number drawing process more attractive, further attracting the attention of the user, and increasing the interest of the number drawing process.

[0048] The preferred embodiments of the present application are specifically described above, but the present application is not limited to the embodiments described above. Those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. These equivalent modifications or replacements are all included in the scope of the present application.
