Description

Reminder with time delay function

The utility model relates to a sitting posture correcting device, in particular to a reminder with a time delay function.

Background technique

The angle sensor of the seat corrector that has been disclosed generally uses a water sensor, such as 93147912.X and 93202588. 9 patent disclosure. Another type is a metal pendulum angular displacement trigger switch, as disclosed in Patent No. 002151316. Due to the large amount of water used in the former, if it is widely promoted, it will seriously pollute the environment after a few years. Although the latter does not pollute the environment, there is a large opening at the handle rotation of the reminder housing due to sitting posture correction, which affects the appearance and is easy to enter foreign objects, making the angle The stability of the displacement switch is poor, and the reminder sound is not adjustable, which wastes material. The above reminder also has a major disadvantage: because it is inevitable to suddenly turn back, stand up, tilt the head forward, backward or pan when using the reminder, at this time the mercury or pendulum that acts as a conductive medium depends on its inertia. Useless reminders appear when the switch is closed, causing noise and annoying the user.

The main circuit of the reminder is the oscillation port 0SC of the programmable voice chip 15 through a resistor. R and switch 4 are connected to the positive electrode of battery 3. The VDD terminal of programmable voice chip 15 is also connected to the positive electrode of battery 3 through circuit switch 4. Its VSS terminal is connected to the negative electrode of battery 3. Its input terminal can be any one of the TG ports (this In the embodiment, TG3 is used.) The angular displacement trigger switch 23 is connected. The output SPK of the programmable voice chip 15 is connected to the base of the switch triode 8050D. The collector of the switch triode 8050D is connected to the positive electrode of the battery 3 through the circuit switch 4 through the sounder 19 The emitter of the triode 8050D is connected to the negative electrode of the battery 3.
