Description

Technical Field

[0001] The present invention relates to the field of amusement equipment, and particularly to a selection device and an amusement machine. Background Art

[0002] Existing lottery amusement machines generally conduct lotteries by selecting balls through a turntable. It includes a rotatably arranged turntable, a retrieval mechanism, a conveying mechanism, and a ball input part located above the turntable. The turntable is provided with a plurality of through holes, and a plurality of lottery bags are installed below the turntable. The plurality of lottery bags are in one-to-one correspondence and communication with the plurality of through holes. During the working process, the lottery balls are put into the rotating turntable through a track by the ball input part. The rotating turntable can stir the lottery balls, so that the lottery balls randomly enter the corresponding lottery bags from a certain through hole on the turntable. The amusement machine determines the lottery result according to the lottery bag into which the lottery ball enters. When it is necessary to retrieve the lottery ball, the retrieval mechanism takes out the lottery ball from the lottery bag and conveys it to the conveying mechanism, and the conveying mechanism conveys the lottery ball from bottom to top to the ball input part. For this kind of lottery amusement machine, it is necessary to set up a retrieval mechanism and a conveying mechanism to re-convey the lottery balls that fall into the lottery bags to the ball input part, resulting in a complex structure and high cost.

[0030] In the description of the present invention, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0031] Refer to Figure 1 , Figure 2 and Figure 4, The sampling device according to the embodiment of the first aspect of the present invention includes a housing 100, a plurality of spheres 700, a ball selection mechanism, a driving mechanism 300, and an identification module 400. The housing 100 is provided with a receiving cavity 110; the plurality of spheres 700 are placed in the receiving cavity 110; the ball selection mechanism is arranged in the receiving cavity 110 and is spaced from the inner wall of the receiving cavity 110. The ball selection mechanism includes a receiving hopper 210 with an upward opening. The ball selection mechanism is provided with at least one ball selection channel 250. The upper end of the ball selection channel 250 is communicated with the receiving hopper 210, and the lower end of the ball selection channel 250 is communicated with the receiving cavity 110. The sphere 700 can enter the ball selection channel 250 from the receiving hopper 210 and then return to the receiving cavity 110 again; the driving mechanism 300 is arranged at the lower end of the receiving cavity 110. The driving mechanism 300 is located below the ball selection mechanism. The driving mechanism 300 can drive the sphere 700 to move upward along the inner wall of the receiving cavity 110 so that the sphere 700 enters the receiving hopper 210.

[0032] The driving mechanism 300 can drive the sphere 700 on the bottom of the receiving cavity 110 to move upward along the inner wall of the receiving cavity 110. When the sphere 700 moves above the receiving hopper 210, the sphere 700 can fall into the receiving hopper 210 under the action of gravity or the sphere 700 is rebounded into the receiving hopper 210 by the inner wall of the receiving cavity 110. And the sphere 700 on the receiving hopper 210 enters the ball selection channel 250 and then returns to the bottom of the receiving cavity 110 again, thus forming a cycle. Among them, the movement routes of the spheres 700 in different positions are different, and the plurality of spheres 700 in the receiving cavity 110 will also interfere with each other's movement, so as to achieve a stirring effect, making the movement route of the sphere 700 random. The sphere 700 entering the ball selection channel 250 is also a random one. Through the above settings, the sphere 700 will automatically return to the receiving cavity 110 after entering the ball selection channel 250 to form a cycle. In this way, the sampling device provided by the present invention does not need to be provided with a retrieval mechanism and a conveying mechanism, thereby streamlining the structure and reducing costs.

[0033] In addition, during the lottery process, there are no exposed moving parts in the sampling device, and it is safer to use. All the spheres 700 will not leave the housing 100, and the situation of losing the spheres 700 can also be avoided.

[0034] In the specific implementation process, when there is one ball selection channel 250, the sphere 700 is provided with an identifier, the ball selection channel 250 is provided with an identification module 400, and the identification module 400 can identify the identifier of the sphere 700 passing through the ball selection channel 250. During the lottery process, the gaming machine determines the lottery result according to the identifier identified by the identification module 400; when there are two or more ball selection channels 250, each ball selection channel 250 is provided with a detection module for sensing the sphere 700. The detection module can be a photoelectric switch, a Hall proximity switch or other detection elements. During the lottery process, the gaming machine can determine the ball selection channel 250 into which the sphere 700 enters through the detection module and then determine the lottery result according to the ball selection channel 250 into which the sphere 700 enters.

[0035] It can be understood that in some embodiments, the ball selection mechanism uses radio frequency identification technology to identify the sphere 700. Specifically, the above-mentioned identifier includes an electronic tag, and one or more of the relevant information such as the color, number, and model of the sphere 700 can be stored in the electronic tag. The identification module 400 includes a reader for reading the electronic tag. Radio frequency identification is a non-contact automatic identification technology. The reader can automatically identify the electronic tag through radio frequency signals and obtain the relevant information such as the color or number of the corresponding sphere 700. The identification work does not require manual intervention, can work in various harsh environments, and is fast and convenient to operate.

[0036] It can be understood that in some embodiments, the identifier can also be the color set on the surface of the sphere 700. Among them, the colors on the surfaces of at least some of the multiple spheres are different. The identification module 400 can include a color sensor or a camera, etc.; of course, the identifier can also be other marks such as numbers, symbols or two-dimensional codes set on the surface of the sphere 700. At this time, the identification module 400 can be set as a camera.

[0037] It can be understood that in some embodiments, when there is one ball selection channel 250, the ball selection channel 250 is provided with a sensor 500, and the sensor 500 is located on the side of the identification module 400 close to the ball receiving hopper 210. The sensor 500 is used to sense the sphere 700. Among them, the sensor 500 can be a photoelectric switch, a Hall proximity switch or other detection elements. The identification module 400 is electrically connected to the sensor 500. When the sensor 500 senses the sphere 700, that is, when the sphere 700 enters the ball selection channel 250, the identification module 400 enters the working state to avoid missed detection caused by the identification module 400 not timely identifying the identifier of the sphere 700. After the identification module 400 completes the identification of the identifier of the sphere 700, the identification module 400 stands by or shuts down.

[0038] Refer to Figure 2 and Figure 3, it can be understood that in some embodiments, when there is one ball selection channel 250, the ball selection channel 250 includes the ball outlet hole 252 of the ball receiving hopper 210 and the deceleration channel 224 arranged in a curved shape. The ball outlet hole 252 is communicated with the deceleration channel 224, and the identification module 400 is arranged in the deceleration channel 224. Thus, the speed of the sphere 700 entering the ball selection channel 250 can be reduced when passing through the deceleration channel 224, the recognition rate of the identification module 400 can be improved, and the situation of missed detection can be avoided.

[0039] Refer to Figures 3 to 6 , it can be understood that in some embodiments, the ball selection mechanism further includes two mounting plates 221 arranged at intervals. The mounting plates 221 are located below the ball receiving hopper 210. A first baffle 222 and a second baffle 223 are installed between the two mounting plates 221. The first baffle 222 and the second baffle 223 are arranged opposite to each other. A first arc surface 2221 is arranged on one side wall of the first baffle 222 close to the second baffle 223. The second baffle 223 extends and protrudes towards the first arc surface 2221 to form a blocking portion 2231. And the second baffle 223 is recessed to form a second arc surface 2232 on the upper side of the blocking portion 2231, and the second baffle 223 is recessed to form a third arc surface 2233 on the lower side of the blocking portion 2231. Thus, the two mounting plates 221, the first baffle 222 and the second baffle 223 enclose to form the deceleration channel 224. The arrangements of the first arc surface 2221, the second arc surface 2232 and the third arc surface 2233 make the deceleration channel 224 curved. When the sphere 700 passes through the deceleration channel 224, the blocking portion 2231 can be used to decelerate the sphere 700. The arrangements of the first arc surface 2221, the second arc surface 2232 and the third arc surface 2233 can also ensure that the sphere 700 will not stay in the deceleration channel 224 to cause blockage of the ball selection channel 250. Among them, the identification module 400 and the sensor 500 can be installed on the mounting plate 221. Since the mounting plate 221 has a flat surface, it is convenient to install the identification module 400 and the sensor 500.

[0040] It should be noted that in the specific implementation process, the above-mentioned ball selection channel 250 can also adopt other setting methods. For example, the ball selection mechanism can include at least one pipeline. Thus, the ball selection channel 250 is formed by the pipeline, and the identification module 400 or the detection module is installed on the pipeline.

[0041] Refer to Figure 1 and Figure 2, it can be understood that in some embodiments, the receiving cavity 110 is spherical. When the sphere 700 at the bottom of the receiving cavity 110 moves upward along the inner wall of the receiving cavity 110 to the upper end of the receiving cavity 110, some spheres 700 can perform projectile motion under their own gravity and thus fall into the ball-catching bucket 210. Among them, part or all of the outer shell 100 is transparent, so that the player can watch the ball selection process, increasing the playability and attractiveness of the amusement machine.

[0042] Refer to Figure 1 , Figure 2 and Figure 4 , it can be understood that in some embodiments, the outer shell 100 includes a first shell 100a and a second shell 100b which are oppositely arranged. The first shell 100a and the second shell 100b are detachably connected by bolts or buckles or the like. The first shell 100a and the second shell 100b enclose to form the receiving cavity 110. Among them, the first shell 100a and the second shell 100b are transparent shells. Through the above arrangement, it is convenient to install components such as the ball selection mechanism and the identification module 400 in the receiving cavity 110.

[0043] Refer to Figure 2 and Figure 4 , it can be understood that in some embodiments, the driving mechanism 300 includes a motor 310 installed on the outer shell 100 and at least one blade 320 rotatably installed at the bottom of the receiving cavity 110. The motor 310 is in transmission connection with the blade 320. The blade 320 is arc-shaped and arranged along the inner wall of the receiving cavity 110. In this way, when the motor 310 drives the blade 320 to rotate, the blade 320 can stir a plurality of spheres 700 and slap the spheres 700, so that the spheres 700 move upward along the inner wall of the receiving cavity 110.

[0044] It can be understood that in some other embodiments, the above driving mechanism 300 can also adopt other setting methods. For example, the driving mechanism 300 can include a plurality of air guns, and the air guns push the spheres 700 to move upward along the inner wall of the receiving cavity 110 by jetting air.

[0045] Refer to Figure 2 and Figure 4, It can be understood that, specifically, the ball selection mechanism further includes a decorative shell 230. The decorative shell 230 is located below the ball receiving hopper 210. The two mounting plates 221, the first baffle 222, and the second baffle 223 are installed inside the decorative shell 230. Among them, the identification module 400 and the sensor 500 are both installed on the mounting plate 221. Through the above arrangement, the decorative shell 230 can protect the identification module 400 and the sensor 500 from being collided by the balls 700 moving in the accommodation cavity 110. Among them, the ball selection channel 250 further includes a first avoidance opening 231 provided at the upper end of the decorative shell 230 and a second avoidance opening 232 provided at the lower end of the decorative shell 230. The ball outlet hole 252 on the ball receiving hopper 210, the first avoidance opening 231, the deceleration channel 224, and the second avoidance opening 232 are connected in sequence. Thus, the balls 700 on the ball receiving hopper 210 pass through the first avoidance opening 231, the deceleration channel 224, and the second avoidance opening 232 in sequence and then return to the accommodation cavity 110 again.

[0046] Refer to Figure 2 and Figure 4 , In the specific implementation process, the decorative shell 230 includes a first cover body 230a and a second cover body 230b which are oppositely arranged. The first cover body 230a and the second cover body 230b are detachably connected by bolts or buckles. The first cover body 230a and the second cover body 230b cooperate with each other to surround the mounting plate 221, the first baffle 222, and the second baffle 223. Through the above arrangement, it is convenient to install components such as the mounting plate 221 and the first baffle 222.

[0047] Refer to Figure 2 and Figure 4 , It can be understood that, specifically, the decorative shell 230 is in a butterfly shape. A light-emitting component 240 is arranged on the outer peripheral wall of the decorative shell 230. The light-emitting component 240 includes a ring-shaped light strip. In the specific implementation process, during the lottery draw, the light strip emits light, and the amusement machine can change the light-emitting color of the light strip according to the lottery draw result. In this way, the ornamental value of the amusement machine can be increased, and the attractiveness of the amusement machine can be improved.

[0048] Refer to Figure 2 and Figure 4, It can be understood that, specifically, at least two connecting members 600 are installed on the top wall of the receiving cavity 110. The connecting members 600 are arranged in the up-and-down direction, and both the ball receiving hopper 210 and the decorative shell 230 are connected to the connecting members 600. Among them, the connecting member 600 includes a bolt 610, a first support sleeve 620 and a second support sleeve 630. The bolt 610 is screwed to the outer shell 100 and passes through the outer shell 100. The two ends of the first support sleeve 610 are respectively abutted against the top wall of the receiving cavity 110 and the ball receiving hopper 210. The two ends of the second support sleeve 620 are respectively abutted against the ball receiving hopper 210 and the decorative shell 230. The bolt 610 sequentially passes through the first support sleeve 620, the ball receiving hopper 210 and the second support sleeve 630, and the bolt 610 is screwed to the decorative shell 230. Thus, through more than two connecting members 600, the ball receiving hopper 210 and the decorative shell 230 can be fixed.

[0049] Referring to Figure 2 and Figure 4 , It can be understood that, in some embodiments, an entrance 120 communicating with the receiving cavity 110 is provided on the outer wall of the outer shell 100, and a cover plate 130 for closing the entrance 120 is detachably installed at the entrance 120. Among them, the entrance 120 is provided at the upper end of the outer shell 100, and the above-mentioned bolt 610 is screwed to the cover plate 130. Thus, through the connecting member 600, the cover plate 130 and the above-mentioned ball selection mechanism can be assembled into a whole. In this way, the cover plate 130 and the ball selection mechanism can be disassembled and assembled as a whole, which is convenient for installation and later maintenance.

[0050] According to the second aspect embodiment of the present invention, it includes the above-mentioned ball selection device. During the lottery process of the gaming machine using the ball selection device, the sphere 700 will automatically return to the receiving cavity 110 after entering the ball selection channel 250 to form a cycle, so that the ball selection device does not need to be provided with a retrieval mechanism and a conveying mechanism, thereby streamlining the structure and reducing the cost.

[0051] In the specific implementation process, the gaming machine further includes a control system, and the control system is electrically connected to the driving mechanism 300. When a lottery is needed, the control system controls the driving mechanism 300 to operate to drive the sphere to move. Among them, when there is one ball selection channel 250, the control system is electrically connected or communicatively connected to the identification module 400, and the control system can determine the lottery result according to the identification information (one or more related information such as the color and number of the sphere 700) identified by the identification module 400; when there are two or more ball selection channels 250, the control system is electrically connected or communicatively connected to the detection module, and the control system can determine the ball selection channel 250 entered by the sphere 700 according to the information fed back by the detection module, and then determine the lottery result according to the ball selection channel 250 entered by the sphere 700. It should be noted that the lottery result is set by the gaming machine and may include but is not limited to the type of prize, the number of prizes, and the win or loss of the game.

[0052] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
