Block triggering warning circuit is alarmed.
Further, the correcting sitting posture and myopia prevention device further include：By the adjustable for height of processor module control
Desk；The processor module is connected with setting button, in Initialize installation, if the head of user and correcting sitting posture and
The distance of myopia prevention device can not meet preset range, then desk is controlled to lift corresponding height by setting button.
Further, elevating mechanism is equipped in two table legs diagonally set in four table legs of the desk, remaining two
Lead is equipped in table leg；And elevating mechanism is using electric pushrod, and the lifting motor in two electric pushrods is by processor
Module synchronization controls.
Further, the warning circuit is voice alarm circuit, and suitable for head and the correcting sitting posture for user and
The distance of myopia prevention device, the body of user are alarmed respectively with the distance of correcting sitting posture and myopia prevention device, with adjustment
The sitting posture of user.
The beneficial effects of the utility model are that this correcting sitting posture and myopia prevention device can detect currently used person automatically
The distance of head, body sends out alarm signal when less than or greater than preset range, and children is prompted to keep correct sitting posture.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the correcting sitting posture of the utility model and the use schematic diagram of myopia prevention device；
Fig. 2 is the correcting sitting posture of the utility model and the functional block diagram of myopia prevention device.
In figure：Correcting sitting posture and myopia prevention device 1, the first ultrasonic sensor 101, the second ultrasonic sensor 102,
Desk 2, elevating mechanism 201, lead 202, user head and correcting sitting posture and the distance L1 of myopia prevention device, make
The body of user and correcting sitting posture and the distance L2 of myopia prevention device.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
As shown in Figure 1, the present embodiment 1 provides a kind of correcting sitting posture and myopia prevention device 1, the correcting sitting posture and near
The desktop of desk 2 is placed in depending on preventing mean 1, and consistent with the initial position of writing hand, and including：Processor module,
First, second ultrasonic sensor being connected with the processor module, wherein the first ultrasonic sensor 101 is obliquely installed upwards
(angle of the first ultrasonic sensor 101 and desktop is 60-80 degree), to detect the head of user and correcting sitting posture and myopia
The distance L1 of preventing mean；Second ultrasonic sensor 102 is horizontally disposed, to detect the body of user and correcting sitting posture and near
Depending on the distance L2 of preventing mean；If the head of user and correcting sitting posture and the distance L1 and/or chest of myopia prevention device with
When correcting sitting posture and the distance L2 of myopia prevention device are below or above corresponding preset range, the processor module triggering alarm
Circuit is alarmed.
By taking the right hand writes as an example, the correcting sitting posture and myopia prevention device are consistent with the initial position of writing hand, i.e.,
Correcting sitting posture and the initial placement position of myopia prevention device are identical with a distance from desktop lower edge with the right hand, correcting sitting posture and myopia
Preventing mean is placed in right-hand lay when starting writing, head and correcting sitting posture and the default model of the distance of myopia prevention device
The preset range for enclosing the distance for 33cm ± 3cm, chest and correcting sitting posture and myopia prevention device is 30cm ± 3cm, more than upper
It states range and carries out warning reminding.
Wherein, such as, but not limited to using STC12C5A60S2, first, second ultrasonic wave passes the processor module
Sensor is such as, but not limited to using HC-SR04.
In order to which the height of desk disclosure satisfy that the correcting sitting posture and myopia prevention device further include using needs：By
The adjustable for height desk of processor module control；The processor module is connected with setting button, in Initialize installation,
