[ On the other hand, the heads 10A and 10B may be formed of a transparent insulating material (e.g., bottle material or silicone), and a popular character may be drawn on the concave head portion 10A containing food.

The body 20 is connected to the heads 10A and 10B and functions as a handle when eating food. The body 20 may be divided into a support and a lid. The lid includes a light-projecting portion 23 that is colored with a character such as a character, a figure or a character, . The support base is provided with grooves on which the head extension portion 10B and the control device 50 can be seated and an opening for connecting the inside and the outside so as to facilitate replacement of the battery 51 that supplies power to the control device 50. [ A space 51 is formed. Normally, the space 51 is covered by the lid 22, and the lid 22 is fixed to the body 20 by fastening means such as bolts.

That is, the sensing circuits 30A, 30B, 30C, and 50 sense an object, light, or heat around the heads 10A and 10B. The sensing circuits 30A, 30B, 30C, and 50 are configured to determine that the heads 10A and 10B contain food and eat the food contained in the heads 10A and 10B according to the sensing results.

Such a sensing circuit may include sensors 30A, 30B, and 30C and a controller 50. [ The sensors 30A, 30B and 30C of the sensing circuits 30A, 30B and 30C can be installed in the heads 10A and 10B and the control device 50 can be installed in the body 20. [ The sensing signals of the sensors 30A, 30B and 30C can be transmitted to the control device 50 via the wirings 31A, 31B and 31C embedded in the heads 10A and 10B. The sensors 30A, 30B and 30C and the wirings 31A, 31B and 31C are protected from the external environment (in particular, moisture) through the waterproof treatment in the heads 10A and 10B, (In particular, moisture) through the waterproofing treatment in the inside of the container 20.

The control device 50 is configured to judge that the heads 10A and 10B contain food in the heads 10A and 10B or eat the foods contained in the heads 10A and 10B in response to changes in the sensing signals output from the sensors 30A, 30B, and 30C do.

When the illuminance sensor and the proximity sensor are installed together, the light emitted from the light emitting element 40A may be detected by the illuminance sensor, so that a judgment error of the controller 50 may occur. Thus, the control device 50 is preferably designed to ignore signals received from the sensors 30A, 30B, and 30C while the output devices 40A and 40B are operating.

The output devices 40A and 40B may include a light emitting device 40A such as an LED that emits light and a speaker 40B that outputs sound.

In the third state (C), the control device may output light, voice of the character, or light and voice to recommend eating the food contained in the spoon according to the sensing result of the sensors. Here, various voices of characters can be output alternately so that the children do not lose interest. After the fifth state (D), the control device can output light, character's voice or light and voice to compliment the eating of the food according to the sensing results of the sensors. Then, it can be initialized again to the first state (A).

The order of eating (putting food on a placed spoon)

3 and 4B, the order of eating the food is the first state A, the sixth state F, the seventh state G, the third state C, the fourth state D, 5 state (D). Likewise, in the third state (C), the light to urge the food, the voice of the character, or the light and voice may be output. Further, after the fifth state (D), the light, the voice of the character, or the light and the voice to praise the food may be output. Then, it can be initialized again to the first state (A).

Food order (eating food in a spoon)

Referring to Figs. 3 and 4C, the order of eating the food proceeds to the first state (A), the third state (C), the fourth state (D), and the fifth state (D). Likewise, after the third state (C) or the fifth state (D), the light, voice of the character, or light and voice may be output. Then, it can be initialized again to the first state (A).

Referring to FIGS. 3 and 4D, the order of eating the food is a first state A, a second state B, a third state C, a second state B, a third state C, 4 state (D) and the fifth state (D). Likewise, after the third state (C) or the fifth state (D), the light, voice of the character, or light and voice may be output. Then, it can be initialized again to the first state (A).

The order of eating (re-eating leftovers in the spoon)

3 and 4E, the order of eating the food is a first state A, a second state B, a third state C, a fourth state D, a third state C, 4 state (D) and the fifth state (D). Likewise, after the third state (C) or the fifth state (D), the light, voice of the character, or light and voice may be output. Then, it can be initialized again to the first state (A).

If you put the empty spoon again

Referring to FIG. 3 and FIG. 4F, when the empty spoon is placed and lifted again, the process proceeds to the first state (A), the sixth state (F), and the first state (A). At this time, even if the first state A becomes the state A in the sixth state F, the current state A of the current state is a state in which the state is completed, according to the fifth sensing result obtained in the previous state and the current first sensing result It is not. That is, the control device controls the output device so that the light or the voice of the character is not outputted according to the result of the fifth sensing and the current first sensing result.

If you put an empty spoon in your mouth

Referring to FIG. 3 and FIG. 4G, when the empty spoon is inserted into the mouth and then removed again, the process proceeds to the first state (A), the fourth state (D), and the first state (A). At this time, since the seventh or eighth sensing result of the fourth state (D) is obtained after the first sensing results of the first state (A) are obtained, the seventh or eighth sensing result of the fourth state (D) Even if the first sensing result of the first state (A) is obtained, the control device judges that the present first state (A) is not the state in which the eating is completed. Thus, the control device controls the output device so that no light or voice of the character is output in the current first state.

If you are not open to food

Referring to FIG. 3 and FIG. 4H, when the food is tilted by the spoon, the state proceeds to the first state (A), the second state (B), and the first state (A). Since the third, fourth, seventh or eighth sensing results of the second state (B) are obtained after the first sensing results of the first state (A) are obtained, Even if the first sensing result of the first state (A) is obtained after the fourth or seventh or eighth sensing result is obtained, the control device determines that the present first state (A) is not the state in which the food is completed. Thus, the control device controls the output device so that no light or voice of the character is output in the current first state.

If the food in the spoon falls

Referring to FIGS. 3 and 4i, when the food in the spoon falls, the state proceeds to the first state (A), the second state (B), the third state (C), and the first state (A). At this time, according to the second, third or fourth sensing result obtained in the previous state (C) and the first sensing result of the current state (A) even if the third state (C) It is determined that the first state (A) of the meal is not completed. That is, the control device controls the output device so that the light or the voice of the character is not output according to the previous second, third, or fourth sensing result and the current first sensing result.

Even if the first sensing result is obtained after the seventh sensing result or the eighth sensing result is obtained, the sensing circuit determines whether or not the sensing circuit is in accordance with the relationship between the previous states and the current state, Or the output of light and voice. That is, even if the first sensing result is obtained after the seventh sensing result or the eighth sensing result is obtained, only when the third state (C) goes through the fourth state (D) to the fifth state (E) The control device determines that it is completed.

As described above, the control device is configured to clearly distinguish each state according to the input order, interval, and timing of the sensing signals input from the sensors, and confirm the continuity of the various states to determine the current state clearly. As a result, the control device can control the output device such that light, sound or both are output only after the food is contained in the head or after the food is completed.

In this way, when the food is in the spoon, it is sensed to output light and sound to encourage the food intake, and after the meal is completed, the spoon is produced so as to output the praise light and sound so that the children can enjoy themselves You can have the right eating habits.

5 is a view for explaining a fork according to an embodiment of the present invention.

5, the fork includes heads 110A, 110B, and 110C, a body 120, sensing circuits 130A, 130B, and 150, and output devices 140A and 140B. The heads 110A, 110B, and 110C and the body 120 are detachable.

The heads 110A, 110B and 110C may include a head portion 110A connected to a plurality of pointed windows 110C for taking food and a head connecting portion 110B connected to the body 120. [ The heads 110A, 110B and 110C may be formed of a transparent insulating material (for example, silicone), and a popular character may be drawn on the surface of the head portion 110A to which the sharp windows 110C to which food is stuck are connected.

The body 120 is connected to the heads 110A, 110B, and 110C and functions as a handle when food is consumed. The body 120 may be configured the same as the body of the spoon.

The output devices 140A and 140B are installed in the body 120 and are configured to output sound, light, or both, under the control of the sensing circuits 130A, 130B, and 150. [ The output devices 140A and 140B may be configured the same as the output device of the spoon.

In comparison of the fork and the spoon, the heads are made of the same material but in different shapes, and the sensors of the sensing circuit are the same, but the positions where the sensors are installed are different and the determination method of the state of the sensing circuit may be different. The remaining components can be configured identically.

The sensing circuits 130A, 130B, and 150 are configured to sense that an object approaches the heads 110A, 110B, and 110C and that an object is away from the heads 110A, 110B, and 110C. The sensing circuits 130A, 130B, and 150 can sense objects, light, or heat around the heads 110A, 110B, and 110C. Also, the sensing circuits 130A, 130B, and 150 determine that the food has been eaten by the heads 110A, 110B, and 110C.

These sensing circuits 130A, 130B, and 150 may include sensors 130A and 130B and a controller 150. [ The sensors 130A and 130B of the sensing circuits 130A and 130B and 150 may be installed in the heads 110A and 110B and the control device 50 may be installed in the body 20. [ The sensing signals of the sensors 130A and 130B may be transmitted to the controller 150 through the wirings 131A and 131B embedded in the heads 110A, 110B and 110C. The sensors 130A and 130B and the wirings 131A and 131B are protected from the external environment (in particular, moisture) through the waterproof processing in the heads 110A, 110B and 110C, (In particular, moisture) through a waterproofing treatment in the case of a water-proofing agent.

The sensing circuits 130A, 130B and 150 may include one sensor 30A or 30B and may include a plurality of sensors 130A and 130B to improve the accuracy of the sensing operation. The control device 150 can be connected to the wirings 131A and 131B of the sensors 130A and 130B by the wirings 150A. The control device 150 may be configured such that food sticks to the heads 110A, 110B, and 110C in response to changes in the sensing signals output from the sensors 130A and 130B, or food sticks to the heads 110A, 110B, and 110C .

The sensor 130B may be installed inside the center of the head portion 110A. In addition, the sensor 130A may be installed inside at least one pointed window 110C of the pointed windows 110C in the head portion 110A. Also, the sensors 130A and 130B may be installed in the center of the head portion 110A and inside the sharp window 110C, respectively.

When the sensor 130A or 130B senses an object, light or heat while only one sensor 130A or 130B is installed on the heads 110A, 110B and 110C, As shown in FIG. If no object, light, or heat is detected by the sensor 130A or 130B, the control device 150 may be configured to determine that the food is eaten. However, if only one sensor 130A or 130B is installed, it can be difficult to clearly determine whether food is stuck or food is eaten. Therefore, it is preferable to install at least two sensors 130A and 130B on the heads 110A, 110B and 110C. Specifically, it is as follows.

It is preferable that the first sensor 130A is installed at such a position that it can not detect an object or heat or detect light when the food is inserted into the pointed window 110C. It is preferable that the second sensor 130B is installed at a position where the head 110A can not sense an object or heat by the body when the head 110A is positioned in the mouth, or can not sense light.

The control device 150 determines that the food is plugged into the pointed window 110C when the sensing signal of the first sensor 130A is activated and the sensing signal of the second sensor 130B is inactive and then the sensors 130A, 130B are all deactivated, it can be determined that the user has eaten the food.

More specifically, the controller 150 controls the first state in which there is no food in the heads 110A, 110B, and 110C according to the sensing signals of the sensors 130A and 130B, the first state in which there is no food in the heads 110A, 110B, and 110C, A second state in which food is plugged in the window 110C, a third state in which the food is plugged in the window 110C, and a fourth state in which the food is fed. For example, when sensing objects or heat are not sensed from the sensors 130A and 130B or sensing signals that are inactivated by sensing external light are transmitted to the control device 150, the control device 150 determines whether the food is plugged in the head (Or an initialization state). When the first sensor 130A senses an object or a heat or does not sense light and the first sensing signal activated and the second sensing signal deactivated from the second sensor 130B are transmitted to the controller 50, The control device 150 determines that the food is in the second state in which the food is plugged into the sharp window 110C of the head portion 110A. Subsequently, when the first and second sensing signals activated from the sensors 130A and 130B are transmitted to the controller 150, the controller 150 determines that the third state is eating the food. Subsequently, when the second and second sensing signals deactivated from the sensors 130A and 130B are transmitted to the controller 150, the controller 150 may be configured to determine the fourth state of eating the food. After the fourth state, it may be initialized to the first state.

In this way, the controller 150 may be configured to distinguish the first state to the fourth state according to the order of change, activation timing, and activation time of the sensing signals input from the sensors 130A and 130B. This order, timing, or time can be appropriately adjusted for accurate sensing and situation determination.

The sensing circuits 130A, 130B and 150 are controlled by the output devices 140A, 140B and 150B so that the voice of the character encouraging the ingestion of the food is output while the light is emitted from the character, , And 140B. Next, when it is determined that the fourth state of eating the food sticking to the heads 110A, 110B, and 110C through the third state, the sensing circuits 130A, 130B, and 150 may detect that the characters praising the eating of the food The control device 150 can control the output devices 140A and 140B so that a voice is output.

The heads 110A and 110B may be provided with an identification device 160 for identifying the type of the head. The sensing circuits 130A, 130B and 150 may be connected to the identification device 160 through the wiring 150A. If the type of the head is identified by the identification device 160, the output devices 140A and 140B ) Can output sound or light differently. For example, the sensing circuits 130A, 130B, and 150 output the voice of the character corresponding to the head type among the various kinds of characters and the predetermined pattern light according to the type of the head identified by the identification device 160 The output devices 140A and 140B can be controlled. On the other hand, some or all of the sensors 130A and 130B may perform the function of the identification device without separately providing the identification device 160. [

The control device described in FIG. 1 and the control device described in FIG. 5 can recognize whether the head connected to the control device by the identification device installed in the head is the head of the spoon or the head of the fork, . In this case, the control device and the output device may be provided in the body, and only the spoon head and the fork head may be used in replacement.
