Description

Technical Field

[0001] The utility model belongs to the field of children's dining chairs, and particularly relates to a children's dining chair with an alarm function. Background Art

[0002] A children's dining chair is a very commonly used children's product, which is a seat specially designed for children to dine, facilitating children's dining and also facilitating adults to take care of children during dining. Existing children's dining chairs only have simple functions such as children's meals.

[0003] For example, a foldable children's dining chair with the publication number CN219166054U includes a backrest. At the middle parts on both sides of the backrest, there are rotatably connected support rod connectors. One end of the support rod connector is provided with a clamping and adjusting mechanism for the backrest. The adjusting mechanism includes a fixed track; at the top of the adjusting plug rod, there is an adjusting handle that is slidably clamped with the backrest. Although it has not only the function of children's meals but also the folding function, it does not have an alarm function. The research results show that the top five causes of children's home injuries are falls / drops (46.81%), burns and scalds (19.75%), knife / sharp object injuries (17.42%), animal injuries (10.73%), and drowning (7.7%). It can be seen that the proportion of falls / drops is very high. During the use of a children's dining chair, if a child's buttocks are separated from the base, such as standing up, etc., it is likely to cause the child to fall from the children's dining chair, posing a safety hazard. And the position of the dining table cannot be adjusted back and forth, and the position for children to enter and exit is narrow, making it inconvenient to enter and exit.

In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and should not be construed as indicating or implying relative importance.

[0042] Such as Figures 1 to 12As shown in the figure, a children's dining chair with an alarm function provided in this embodiment includes support feet 1, a base 2, a backrest 3, a cushion 4, a pressure sensor 5, a controller 6, a buzzer 7, a storage battery 8, a touch display screen 9, a speaker 10, and a communication module 11.

[0043] The base 2 is fixed to the support feet 1, the backrest 3 is arranged on the base 2, the top surface of the bottom of the base 2 has a horizontal plane 21, the pressure sensor 5 is arranged on the horizontal plane 21, the controller 6 is arranged on the backrest 3, a cushion 4 is arranged on the front side of the backrest 3, the controller 6 is located between the cushion 4 and the backrest 3, the pressure sensor 5 is located between the cushion 4 and the base 2, the buzzer 7 is arranged at the bottom of the base 2, the pressure sensor 5 is electrically connected to the controller 6, and the controller 6 is electrically connected to the buzzer 7. The storage battery 8 is installed at the bottom of the base 2, and the storage battery 8 is electrically connected to the controller 6. The touch display screen 9 is arranged on the rear side wall of the backrest 3 and is arranged opposite to the controller 6, the speaker 10 is arranged on the left and right outer side walls of the base 2, and both the touch display screen 9 and the speaker 10 are electrically connected to the controller 6. The controller 6 is electrically connected to the communication module 11, and the communication module 11 is communicatively connected to a mobile terminal.

With the placement-type dinner plate 13, the dinner plate 13 can be removed for cleaning, which is more convenient. Through the setting of the retaining post 14, it is avoided that children slide down from the space between the base 2 and the dining table 12, further improving safety.

[0047] Among them, the dining table 12 includes a cross arm 121, a table body 122, a spring 123, and a catch bead 124. Cross arms 121 are arranged on both the left and right sides of the top of the base 2. Both the left and right sides of the bottom of the table body 122 have sliding grooves 125, and the cross arm 121 is slidably matched with the sliding grooves 125. Both the left and right sides of the sliding grooves 125 have accommodation grooves 126, and the accommodation grooves 126 communicate with the sliding grooves 125. A spring 123 is fixed in the accommodation groove 126, and the inner end of the spring 123 is fixed with a catch bead 124. The catch bead 124 is slidably matched with the accommodation groove 126. A number of card slots 127 are arranged on both the left and right side walls of the cross arm 121, and the number of card slots 127 are equally spaced along the length direction of the cross arm 121. The catch bead 124 is matched with the card slots 127. When the front and rear positions of the table body 122 need to be adjusted, push the table body 122, the spring 123 contracts, and the catch bead 124 retracts into the accommodation groove 126 until the catch bead 124 moves to the next card slot 127, and the spring 123 elongates, driving the catch bead 124 to snap into the current card slot 127 for fixed limit. In this way, only by simply pushing the table body 122 forward and backward with force can the front and rear adjustment of the table body 122 be realized, and no additional operation is required after adjustment, and the table body 122 can be kept in the current position. There is no need for a complex structure or complex operation to realize the front and rear positions of the table body 122, providing more space for children to enter and exit, and the dining distance can also be adjusted according to different children.
