Description

Technical Field

[0001] This utility model relates to the field of infant and toddler products technology, and more specifically to a multifunctional infant and toddler dining chair. Background Technology

[0002] There are various types of baby high chairs on the market, some foldable and some non-foldable. A common foldable type is a foldable baby high chair disclosed in Chinese Patent No. 201620535027.5, which includes a table, armrests, armrest supports, a seat, a backrest, and a backrest support. One end of the armrest support is hinged to the seat, and the other end of the armrest support is hinged to both the table and the armrest. One end of the backrest support is hinged to the seat, and the other end is hinged to the armrest. The backrest is fixedly mounted on the backrest support. The hinge joints of the table, armrests, and armrest supports are equipped with locking and unlocking mechanisms. The locking and unlocking mechanisms include a locking element, a locking groove, and a first unlocking button. The locking groove engages the locking element to lock the hinge joint, and the first unlocking button disengages the locking element from the locking groove to unlock the hinge joint. The locking and unlocking mechanisms also include a first reset element to reset the locking element and the first unlocking button. By pressing the first unlocking button, the high chair can be folded or unfolded, making it convenient to carry when going out. These common foldable high chairs for infants and toddlers do not have the function of heating the plate, meaning they do not have the structure to keep the plate warm, nor do they have the function of heating the seat, so they cannot keep the temperature of the toddler's bottom warm. Utility Model Content

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0019] It should be noted that when an element is said to be "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please refer to Figures 1 to 6 This utility model provides a multifunctional infant high chair, comprising a base shell 10, a backrest portion 20 integrally connected to the rear side of the base shell 10, a seat portion 30 connected to the front side of the base shell 10, a support frame 40 rotatably connected to the backrest portion 20, and a dining table 50 disposed on the support frame 40. In actual use, the support frame 40 can rotate relative to the backrest portion 30, so that the dining table 50 is positioned above the seat portion 30, facilitating dining for infants.

[0022] In this embodiment, the dining table 50 includes a support platform 51 and a first heater 52. The support platform 51 has an inner cavity 511. The bottom of the support platform 51 has a heating pipe 512 that communicates with the inner cavity 511. The first heater 52 is disposed in the heating pipe 512. The first heater 52 includes a PTC heating element 521 and a fan 522. When the PTC heating element is working, the fan can generate hot air. The hot air is blown into the inner cavity 511 through the heating pipe 512. The top surface of the support platform 51 has at least one plate window 513 and several ventilation holes 514. The plate window 513 is for the user to place the plate. After the plate is placed in the plate window 513, the warm air generated by the first heater 52 keeps the food in the plate warm. The ventilation holes 514 ensure that the warm air can smoothly enter the inner cavity 511. The warm air can also overflow from the ventilation holes 514 to increase the temperature near the child's arm and increase comfort. It is worth mentioning that, in order to ensure a suitable temperature, the maximum temperature of the heating system can be set at around 25°C, and the power will be cut off if it exceeds 25°C.

[0023] In this embodiment, the bottom shell 10 is provided with two air inlets 21. One air inlet is provided with a second heater with the same structure as the first heater (not shown in the figure, but the structure can be referred to as the first heater). The second heater supplies heat to the inside of the bottom shell 10. The bottom of the bottom shell 10 is fixed with a bottom plate 212 so that the heat can flow in the internal space of the bottom shell 10. The other air inlet is used to ensure the flow of heat so that the internal space of the bottom shell 10 can be connected with the external space to form air flow.

[0024] In this embodiment, the seat portion 30 is provided with an insertion port 31 for inserting the heating pipe. The support frame 40 includes a U-shaped body 41 with both ends mounted on both sides of the backrest portion via locking and unlocking mechanisms, and a wrapping body 42 connected to the middle of the U-shaped body 41 and wrapped around the heating pipe 512. The specific structure of the locking and unlocking mechanism can be found in a foldable infant high chair disclosed in Chinese Patent No.: 201620535027.5. The two ends of the U-shaped body 41 can also be directly connected to both sides of the backrest portion via pivots, as long as the support frame 40 can rotate. The rotation effect of the support frame 40 is not the focus of this utility model and will not be described in detail here.

[0025] In this embodiment, as Figures 3 to 5As shown, a guidance system is also provided on the support platform 51 of the dining table 50. The guidance system includes a weighing sensor 61 located below the plate window 513, a microcontroller 62 located inside the support platform 51, an LED light strip 63 located on the top surface of the support platform 51, a speaker 64 located on the top surface of the support platform 51, a lithium battery 65 located inside the support platform 51, and an LCD display screen 66 located on the support platform 51. The microcontroller is connected to the weighing sensor 61, the LED light strip 63, the speaker 64, the LCD display screen 66, and the lithium battery 65. The weighing sensor is an HX711 type weighing sensor, and the microcontroller is an Arduino.

[0026] The guiding system works as follows: a weighing sensor detects the weight of the plate in real time and converts the weight signal into an electrical signal. The microcontroller reads the electrical signal, converts it into a digital quantity, and calculates the current weight. The microcontroller continuously monitors weight changes via the LCD display. When a weight decrease exceeds a certain threshold (e.g., 5 grams) and persists for a certain period (to avoid false alarms), it is determined that a bite has been taken. Upon determining that a bite has been taken, the microcontroller triggers a speaker to play a preset encouraging sound effect and simultaneously controls the LED light strip display module to flash. The lithium battery provides a stable voltage for the entire system.

[0027] The present invention aims to provide warmth to the outside of the plate through the first heater, thereby keeping the plate warm; to increase the temperature of the seat area through the second heater, thereby improving comfort; and to accurately detect the infant's eating behavior and provide timely and interesting feedback through the guidance system, thereby increasing the fun of eating.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
