The invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-4, the present embodiment provides an intelligent timer, which includes a housing 10, a mechanical movement 20 disposed on the housing 10, and a rotating cover 30 disposed on the mechanical movement 20 and in transmission connection with a spring rod 21 of the mechanical movement 20, wherein the mechanical movement 20 has a shift fork 22 for being shifted after the completion of the timing, the mechanical movement 20 having the spring rod 21 of the shift fork 22 is a conventional movement, and is widely used in various types of mechanical timers, and the specific connection structure between the mechanical movement 20 and the housing 10 and the rotating cover 30 is also the same as the structure of the mechanical timer, which is not a main point of the present embodiment, and will not be described in detail herein.

The shell 10 is a revolving body, the mechanical movement 20 is located in the middle of the shell 10, the upper end of the shell 10 is provided with a ring groove 11 surrounding the mechanical movement 20, and the shell 10 is provided with time scale marks arranged around the ring groove 11. The rotating cover 30 is covered on the mechanical movement 20, the middle position of the inner cavity of the rotating cover is fixedly connected with the spring rod 21 of the mechanical movement 20 through an inserting structure, the periphery of the rotating cover 30 is embedded into the ring groove 11, and a gap is formed between the periphery of the rotating cover 30 and the groove bottom of the ring groove 11, so that the gap between the rotating cover 30 and the shell 10 is hidden, and the appearance is more attractive. In addition, a pointer or an arrow that fits the time scale line is provided on the rotating cover 30.

The case 10 is further provided with a power source 41, a capacitor 42, a sound IC43 and a change-over switch 44 connected to each other to form a circuit, wherein the change-over switch 44 has a first terminal 51 electrically connected to a first pole of the power source 41, a second terminal 52 electrically connected to a control terminal of the sound IC43, and a movable terminal 53 for engaging with the shift fork 22, such a change-over switch having three terminals is commercially available directly, one end of the capacitor 42 is electrically connected to the movable terminal 53, the other end is electrically connected to a second pole of the power source 41, and two power input terminals of the sound IC43 are electrically connected to two poles of the power source 41 one-to-one, respectively, to supply power to the sound IC 43. In addition, an indicator lamp 45 is electrically connected between the movable terminal 53 and the second pole of the power supply 51 in parallel with the capacitor 42 so that the user can know whether the power supply 41 is powered.

In the initial state, the mechanical movement 20 is in a device which stops working, the spring of the mechanical movement does not store energy, the capacitor 42 is not charged, the pointer or the arrow points to the zero scale line of the time scale line, the shift fork 22 is in the unstripped position at this time, the movable terminal 53 of the change-over switch 44 is electrically connected with the second terminal 52, and the control end of the audio IC43 does not receive an electric signal and does not make a sound because the capacitor 42 is not charged. When the rotating cover 30 is rotated, a pointer or an arrow point to a scale mark corresponding to a time length which a user wants to set, in the process, a spring rod 21 of the mechanical movement 20 is screwed, the mechanical movement 20 stores energy, meanwhile, a shifting fork 22 is shifted and triggers a change-over switch 44, a movable terminal 53 of the change-over switch 44 is switched to a position electrically connected with a first terminal 51, a power source 41 charges a capacitor 42, after the rotating cover 30 stops rotating, the mechanical movement 20 is in a working state, energy release is started to time, and at the moment, the shifting fork 22 still keeps a shifted state; during the timing process, the spring of the mechanical movement 20 gradually releases the stored energy, the rotating cover 30 is driven by the spring rod 21 to slowly rotate to change the direction of the pointer or the arrow, after the stored energy of the spring of the mechanical movement 20 is completely released, the pointer or the arrow points to the zero scale line of the time scale line, the mechanical movement 20 stops working, the shifting fork 22 is reset, and further the movable terminal 53 of the switch 44 is electrically connected with the second terminal 52 again, at this time, because the capacitor 42 is charged, the control terminal of the sound IC43 receives the electric signal and makes a sound, the duration of the sound is determined by the electric quantity of the capacitor 42, and after the electric quantity of the capacitor 42 is exhausted, the sound IC43 stops making the sound, and the timing reminding function is completed.

It should be noted that the specific matching structure between the shift fork 22 and the switch 44 may be a conventional structure, and preferably, in this embodiment, a through hole 12 is formed on the inner side wall of the ring groove 11, a notch 31 arranged corresponding to the through hole 12 when the mechanical movement stops (i.e. in an initial state) is formed on the rotating cover 30, and the switch 44 is disposed at a position corresponding to the through hole 12, and is located at two sides of the through hole 12 respectively with the notch 31. The shifting fork 22 is a spring plate with one end connected to the switch 44, the switch 44 is further provided with a switch contact matched with the spring plate, the other end of the spring plate is fixedly connected with a ball head inserted into the through hole 12, and the switch 44 with the spring plate and the switch contact can also be directly purchased from the market. In the initial state, the mechanical movement 20 stops working, the ball head is inserted into the notch 31 at the same time, and when the mechanical movement 20 is in the working state, because the rotating cover 30 is rotated at this time, the position of the notch 31 no longer corresponds to the position of the through hole 12, the ball head is forced to be separated from the notch 31, so that the elastic sheet is pressed and stirred, and further the elastic sheet is abutted against the switch contact, and the change-over switch 44 is triggered to execute the change-over action.

The present invention has been described in detail with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments, and those skilled in the art can modify the present invention according to the prior art, for example, the sound IC43 in the above embodiments is changed to other electric sounding elements such as a horn, and these elements are all included in the protection scope of the present invention.
