Description

Technical Field

[0001] This utility model belongs to the field of electronic toy technology, specifically relating to a lottery toy. Background Technology

[0002] Lottery toys are a common type of toy. The main gameplay involves two or more players drawing lots in a freely chosen manner, with a system of rewards and punishments to create a fun game. This type of toy is perfect for playing at gatherings with friends and has a wide appeal worldwide.

[0003] A common type of lottery toy is the "lottery fry." This type of toy is shaped like French fries, with a French fries box as its base, inside which are placed several French fry-shaped "lottery slips." For example... Figure 1 As shown, some of the fries have thin strings attached to their bottoms, with the other end of the strings connected to a switch inside the base. Players take turns drawing fries by lottery. When a player draws a fries with the string attached, they pull the mechanical switch inside the base, popping all the fries out. However, this mechanical triggering structure suffers from low randomness and a small triggering action, which diminishes the toy's fun factor.

[0004] Another common lottery toy is the "pirate barrel." This toy is typically shaped like a round wooden barrel, with pirate-themed figurines on top and multiple long, narrow holes in the body. Players take turns inserting knife-shaped "slips" into one of the holes. A trigger switch is located in a specific hole; when a "lucky" player selects that hole and inserts their slip, the switch is triggered, causing the figurine on top to pop upwards with a loud sound, creating a scare effect and adding to the game's fun. Chinese utility model patent CN205434991U discloses a "Precarious Pirate Barrel," whose launching assembly includes a mechanism outer cylinder, a launching base, a spring, and a mechanism triggering device. The triggering device includes a trigger switch, a rebound plate, and a mounting base. This toy uses a mechanical switch for triggering. On the one hand, the hole corresponding to the trigger switch is preset at the factory and cannot be changed, so repeated play will reduce the fun. On the other hand, the sensitivity of the mechanical switch will be affected by repeated use, causing problems such as the figure not popping out after being triggered, which will affect the play experience. Utility Model Content

[0005] The purpose of this invention is to provide a lottery toy that uses an electronic triggering device to detect the number of lottery tickets through a photosensitive element and has a built-in random value. When the detected value reaches the random value, an action is triggered, which has high randomness and can improve the playing experience and fun.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A lottery toy includes a base, the base including an inner cavity surrounded by a shell and a cover plate, the shell protruding from the outer surface of the cover plate to form a receiving cavity for placing a lottery ticket, and a triggering component for realizing a triggering action is provided in the inner cavity.

[0008] The cover plate is a light-transmitting cover plate, and the inner cavity is also provided with a detection component and a data processing component; the data processing component is circuitically connected to the detection component and the trigger component, and is connected to a power supply;

[0009] The detection component includes a detection device capable of receiving light and detecting light intensity; the data processing component can read the light intensity data detected by the detection component in real time; the data processing component includes a processor that can generate random numbers internally and send an instruction to the triggering component when the real-time read light intensity data reaches the random number, causing the triggering component to perform a triggering action.

[0010] In this invention, "inner" and "outer" refer to the inner cavity.

[0011] The principle behind this lottery toy design is that external light can only enter the inner cavity through a light-transmitting cover. During play, players place game slips into the cavity, which act as a barrier, weakening the light intensity entering the cavity. As the game progresses, players continuously draw slips, reducing the number of slips and thus weakening the light barrier, increasing the light intensity entering the cavity. The detection component detects this change in real time and relays it to the data processing component, thereby detecting the number of slips in the cavity. Combined with a random value generated by the processor at the start of each game, when the detected light intensity reaches that random value, a trigger action is issued, enabling the lottery toy to activate when a player "wins" a draw. Compared to traditional lottery toys, this design offers greater randomness and allows for repeated play, effectively increasing the toy's fun. The trigger action can be achieved through various methods, such as playing sound effects, emitting light effects, or making a pop-up motion.

[0012] In one specific embodiment of this utility model, the cover plate is movable relative to the outer shell, and the triggering component includes an ejection component disposed toward the cover plate. This design allows the triggering component to perform an ejection action via the ejection component when it receives a command, pushing the cover plate outward and causing the remaining slips placed in the receiving cavity and on the cover plate to spring up, achieving a certain startling effect and thus enhancing the feedback of the lottery toy.

[0013] The power source of this invention can be an external power source or a built-in battery.

[0014] In one specific embodiment of this utility model, the detection device is a phototube. As the intensity of light received by the phototube changes, the base current of the phototube also changes accordingly. By detecting the change in current, the change in the intensity of light entering the inner cavity is reflected.

[0015] In one specific embodiment of this utility model, a light-shielding device is provided on the outer shell. By providing a light-shielding component, light can be further blocked, ensuring that light can only pass through the cover plate into the inner cavity. This allows for better control of the intensity of light entering the inner cavity, controlling the maximum value of the light intensity measured by the detection component, and ensuring the sensitivity of detecting changes in light intensity, thereby enabling the lottery toy to be triggered smoothly. The light-shielding component can be an independent light-shielding sleeve provided on the outer shell, or it can be a light-shielding layer integrally formed with the outer shell.

[0016] In one specific embodiment of this utility model, the cover plate is provided with one or more light-transmitting points, and the thickness of the light-transmitting points is less than the thickness of the cover plate. The light-transmitting points increase the intensity of light passing through the cover plate and entering the inner cavity, better ensuring that the lottery toy can be triggered smoothly. In a preferred embodiment, the thickness of the light-transmitting points is one-third of the cover plate thickness.

[0017] In one specific embodiment of this utility model, the phototube can be an NPN type phototube or a PNP type phototube.

[0018] In one specific embodiment of this utility model, the detection component circuit is connected between the power supply and the data processing component, and the detection component includes one or more detection units, each detection unit including at least one phototube.

[0019] The detection unit is connected to one pin of the processor. The detection unit includes a capacitor, a resistor and a phototube. One end of the phototube and the capacitor is grounded, and the other end is connected to one end of the resistor and the pin of the processor. The other end of the resistor is connected to the power supply.

[0020] In another specific embodiment of this utility model, the detection unit is connected to a pin of the processor. The detection unit includes a capacitor, a resistor and a phototube. One end of the resistor and capacitor is grounded, and the other end is connected to one end of the phototube and the pin of the processor. The other end of the phototube is connected to the power supply.

[0021] This design amplifies the base current change of the phototube in the detection unit, effectively improving the sensitivity to detecting changes in light intensity; at the same time, it greatly simplifies the circuit and reduces the production cost of toys.

[0022] In one specific embodiment of this utility model, the ejection assembly includes a motor with a pinion, a spring seat, a compression spring, a support rod, and a limiting member. The compression spring is mounted on the spring seat, and the support rod is mounted on the top of the compression spring. The top of the support rod contacts the inner side of the cover plate. The limiting member is a fan-shaped limiting member, with its center rotatably connected to the bottom of the spring seat. The limiting member has teeth along an arc and meshes with the pinion of the motor. The support rod has protrusions on both sides for limiting, and the limiting member has grooves for limiting. The protrusions of the support rod are installed in the grooves, and the end of the grooves has a vertical section, allowing the support rod to move back and forth in a straight line along the direction of the compression spring.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. This invention utilizes a photosensitive element to detect light intensity, thereby detecting the number and changes in the number of lottery slips. It also employs an internally set random value to trigger the toy's mechanism. Compared to traditional lottery toys, it offers greater randomness, stronger feedback, and allows for repeated play, significantly enhancing the toy's appeal.

[0025] 2. Compared to traditional lottery toys, the number of lottery tickets in this invention is more flexible. Players can choose the number of lottery tickets to place according to the actual situation without affecting normal gameplay.

[0026] 3. Compared to traditional lottery toys that use mechanical triggers, this one offers a stronger sense of feedback and greater randomness. Furthermore, when placing the lottery tickets, there is no need to match each ticket to the trigger switch, making it more convenient to play.

[0027] 4. The circuit of this utility model effectively improves the sensitivity of detecting changes in light intensity, and at the same time, the design is simpler, thereby reducing the production cost of toys. Attached Figure Description

Detailed Implementation

[0041] The present invention will be further described below through specific embodiments. Example 1

[0042] like Figures 2-5 As shown, the lottery toy is shaped like French fries, comprising a French fry box base 1 and several French fry-shaped toy slips 2. The French fry box base 1 includes an outer shell 3, which is a barrel-shaped structure with openings at the top and bottom. A transparent spring plate 4 is disposed within the outer shell 3, dividing it into an upper cavity and a lower cavity. The upper cavity is used to hold the toy slips 2, while the lower cavity contains a battery, a trigger component 7, a light detection component, and a processing component 8 for processing and issuing commands to the trigger component 7. A base plate 9 is provided at the bottom of the lower cavity. The outer shell 3 is provided with a light-shielding layer, allowing external light to only penetrate the lower cavity through the transparent spring plate 4.

[0043] The processing component 8 includes a circuit board 81 fixedly mounted on the base plate 9. A light detection component, comprising a phototube 82, is electrically connected to the circuit board 81 and mounted on the circuit board 81. The circuit board 81 is equipped with a processor for processing signals and issuing commands. This processor can read the current value of the phototube 82 in real time and identify the light intensity received by the phototube 82 at that moment based on the current value. The processor can also internally generate a random value X as a trigger value.

[0044] The trigger assembly 7 includes a spring seat 71, a compression spring 72 mounted on the spring seat 71, and a support rod 73 mounted on the top of the compression spring 72. The top of the support rod 73 contacts the transparent spring plate 4. A fan-shaped limiting member 74 is rotatably connected to the bottom of the spring seat 71, and the limiting member 74 has teeth along an arc. The support rod 73 has protrusions on both sides for limiting, and the limiting member 74 has grooves for limiting, in which the protrusions of the support rod 73 are installed. The trigger assembly 7 also includes an electric motor 5 with a pinion gear. The electric motor 5 is fixedly mounted on the base plate 9 via a mounting base 6. The electric motor 5 is electrically connected to the circuit board 81. The mounting base 6 also has a gear 51 that meshes with the pinion gear, and the gear 51 meshes with the teeth of the limiting member 74.

[0045] This design of the French fry lottery toy allows light to pass through the transparent spring plate 4 into the lower cavity and reach the photosensitive tube 82. For example... Figure 6 As shown, when the toy tag 2 is placed on the transparent spring plate 4, it blocks the light entering the lower cavity. As the game progresses, the number of toy tags 2 is continuously reduced by removing them, and their blocking of light weakens accordingly. This allows the phototube 82 to detect the increasing light intensity, thus enabling the detection of the number of toy tags 2 on the transparent spring plate 4. Furthermore, before each game begins, the processor pre-generates a random value. When the light intensity detected by the phototube 82 reaches this random value, the instruction triggering component 7 is activated.

[0046] The base 1 of the French fry box is equipped with a speaker 10, which is connected to the circuit board 81, allowing it to play music during play and increasing the toy's fun. A soft pad 11 is also provided on the bottom of the base plate 9 to ensure stability. A switch 12 connected to the circuit board 81 is located on one side of the outer casing 3, used to control the toy's opening and closing. A decorative panel 13 is also provided on the outer casing 3 for decorative purposes.

[0047] When starting to play, press switch 12 to turn on the power, and the speaker 10 will start playing music. At the same time, the processing component 8 automatically generates a random value. Manually pressing the transparent cover 4 causes the support rod 73 to retract downwards. The protrusions on both sides of the support rod 73 move downwards with the support rod 73, driving the limiting member 74 to rotate. When the support rod 73 reaches the bottom, the limiting member 74 acts as a limit, preventing the support rod 73 from springing back. Place the toy tag 2 in the upper cavity and on the transparent spring plate 4. As playing progresses, the toy tag 2 is continuously removed, and the number decreases. The light entering the lower cavity gradually increases, and the photosensitive tube 82 continuously detects the light intensity. When the real-time light intensity value read by the processor reaches the internally set random value, the processor sends a command to the electric motor 5 to rotate, which in turn drives the gear 51 and the limiting member 74 to rotate. After the limiting member 74 rotates, its limiting effect on the support rod 73 disappears. The support rod 73 rebounds upward and resets under the action of the compression spring 72, and pushes the transparent spring plate 4 upward, so that the remaining toy slips 2 are all popped out under the action of the transparent spring plate 4, thereby triggering the winning lottery in the lottery game. Example 2

[0048] like Figure 7 As shown, the difference between Example 2 and Example 1 is that:

[0049] The transparent spring plate 4 has several light-transmitting points 41, and the thickness of the transparent material at the light-transmitting points 41 is only one-third of the thickness of the transparent spring plate 4. This design can improve the light transmittance at the light-transmitting points, thereby better controlling the light intensity received by the photosensitive tube 82 within a suitable range, and enabling the lottery toy to be triggered normally even in low ambient light conditions.

[0050] The processor also includes a timing device that generates a random time value before the start of each game. When the timer reaches zero, the processor will issue a command regardless of whether the real-time light intensity value reaches or exceeds the internally set random value. The command triggers component 7 to perform an action. Example 3

[0051] like Figure 8 As shown, this embodiment, based on embodiment 1, has the following circuit configuration: the photodetector component includes multiple detection units, one end of each detection unit is connected to a pin of the processor, and the other end is connected to a power supply. During operation, the processor continuously reads the current magnitude of the integrated circuit and reflects the current photosensitive value accordingly.

[0052] Each detection unit contains a phototube Q. X Resistance R x and capacitor C x Q phototube X One end, capacitor C xOne end of the phototransistor Q is grounded. X The other end and capacitor C x The other end is connected to resistor R x One end and the processor's pin PA x Connection, resistor R x The other end is connected to the power supply.

[0053] Phototube Q X An NPN phototransistor is used, in which light intensity is negatively correlated with the current of the integrated circuit. The processor reads and records the current of the integrated circuit in the initial state and sets it as the photosensitive base value V.

[0054] At the start of each game, the processor automatically generates a random number X, where X < V. During the game, the processor continuously reads the current value of the integrated circuit and records it as a real-time light intensity value V'. As the toy tags on the transparent board are gradually removed, the value of V' continuously decreases. When V' ≤ X, the processor sends a command to the triggering component to trigger an action.

[0055] Compared to traditional mechanical triggering circuits containing several switches, or photosensitive circuits that commonly use the IR reflection receiving principle, this circuit design is simpler in structure and effectively reduces overall production costs. Example 4

[0056] like Figure 9 As shown, the difference between this embodiment and Embodiment 3 is that:

[0057] Phototube Q X Using a PNP phototransistor, the light intensity is negatively correlated with the current of the integrated circuit, and when the processor automatically generates a random number X, X < V. During the game, as toy tags on the transparent board are gradually removed, the value of V' continuously decreases. When V' ≤ X, the processor sends a command to the triggering component, causing it to perform a trigger action. Example 5

[0058] like Figure 10 As shown, the difference between this embodiment and Embodiment 3 is that:

[0059] The resistor R in each detection unit x One end, capacitor C x One end of each resistor is grounded, and the resistor R x The other end and capacitor C x The other end is connected to the phototube Q. X One end and the processor's pin PA x Connection, phototube Q X The other end is connected to the power supply.

[0060] In this setup, the light intensity is positively correlated with the current of the integrated circuit. Furthermore, when the processor automatically generates a random number X, X > V. As the game progresses, the value of V' continuously increases as toy tags are gradually removed from the transparent board. When V' ≥ X, the processor sends a command to the triggering component, causing it to perform a trigger action. Example 6

[0061] like Figure 11 As shown, the difference between this embodiment and Embodiment 5 is that:

[0062] Phototube Q X A PNP phototransistor is used. With this setup, the light intensity is positively correlated with the current of the integrated circuit. Furthermore, when the processor automatically generates a random number X, X > V. During the game, as toy tags are gradually removed from the transparent board, the value of V' continuously increases. When V' ≥ X, the processor sends a command to the triggering component, causing it to perform a trigger action.

[0063] It should be noted that the above embodiments are merely further illustrations of the present utility model, and not limitations. Any adjustments or changes made by those skilled in the art within the equivalent meaning and scope of the technical solution of the present utility model should be considered as included within the protection scope of the present utility model.
