[0042] Combine the following Figures 1 to 7 The multifunctional timing device of the utility model is described in detail.
[0043] The embodiment of the utility model discloses a multifunctional timing device, such as Figure 1 As shown, it includes: a timer body, a rotating component and a knowledge content piece 4.
[0044] The timer body is used for countdown, and the timer body includes a housing 1 and a timing module 2 arranged in the housing 1 . A timing display window is arranged on the end face of the housing 1 , and a circle of step surface 112 is arranged on the side face of the housing 1 .
[0045] In a specific embodiment of the present invention, Figure 3 and Figure 4 As shown, the shell 1 includes a face shell 11 and a bottom shell 12. A first connecting column 111 is arranged inside the face shell 11, and a second connecting column 121 is arranged inside the bottom shell 12. In this embodiment, the second connecting column 121 is a hollow column. The inner diameter of the second connecting column 121 matches the outer diameter of the first connecting column 111. The face shell 11 and the bottom shell 12 are quickly connected by inserting the first connecting column 111 into the second connecting column 121.
[0046] The end of the face shell 11 is provided with a first groove 113 and a second groove 117, the second groove 117 is provided at the groove bottom of the first groove 113, and the first groove 113 and the second groove 117 form a timing display window. The first groove 113 is a circular groove, and the second groove 117 is a circular groove.
[0047] The shell 1 described in this embodiment is cylindrical as a whole, and the front shell 11 and the bottom shell 12 are both columnar structures with one end open and a section closed, and the front shell 11 and the bottom shell 12 are butt-jointed together.
[0048] Since the face shell 11 of the present embodiment is provided with a step surface 112, the outer diameter of one end of the face shell 11 is slightly smaller than the inner diameter of the bottom shell 12, so that the end of the face shell 11 with a smaller outer diameter is sleeved together with the bottom shell 12. At the same time, the face shell 11 of the present embodiment is provided with a first limit buckle 116, and the bottom shell 12 is provided with a second limit buckle 124. The first limit buckle 116 is arranged on the outer wall of the face shell 11, and the second limit buckle 124 is arranged on the inner wall of the bottom shell 12. After one end of the bottom shell 12 is sleeved on the end with a smaller outer diameter of the face shell 11, the face shell 11 or the bottom shell 12 is rotated to put the first limit buckle 116 and the second limit buckle 124 together, so as to further fix the bottom shell 12 and the face shell 11. The first limit buckle 116 and the second limit buckle 124 of the present embodiment are both strip-shaped protrusions, and a plurality of first limit buckles 116 and second limit buckles 124 are respectively arranged along the circumference of the face shell 11 and the circumference of the bottom shell 12.
[0049] In this embodiment, reinforcing ribs 122 are further provided on the inner wall of the bottom shell 12. Since the timing module 2 is supported inside the bottom shell 12, the strength of the bottom shell wall is enhanced by providing the reinforcing ribs 122. The reinforcing ribs 122 are arranged in sequence along the circumferential direction of the inner wall of the bottom shell 12.
[0050] In a specific embodiment of the present invention, Figure 5As shown, the timing module 2 includes a dial 21, an active color piece 22 and a movement 23. The movement 23 is arranged in the housing 1, and a rotating shaft 231 is arranged on the movement 23; a second hole 115 for the rotating shaft 231 to pass through is arranged on the end surface of the face shell 11. The dial 21 is circular, and the diameter of the dial 21 matches the outer diameter of the first groove 113. The dial 21 is arranged in the first groove 113. Specifically, the dial 21 can be bonded to the bottom of the first groove 113. The dial 21 is provided with a third hole 211 for the rotating shaft 231 to pass through and a first opening 212 for the active color piece 22 to pass through. The active color piece 22 is arranged between the dial 21 and the face shell 11, and the diameter of the active color piece 22 matches the diameter of the second groove 117, and the active color piece 22 is arranged in the second groove 117. The movable color sheet 22 is connected to the rotating shaft 231 . The rotating shaft 231 drives the movable color sheet 22 to rotate, so that the movable color sheet 22 passes through the first opening 212 and covers the surface of the dial 21 or returns to the bottom of the dial 21 .
[0051] In this embodiment, the first opening 212 of the dial 21 is at the 0 scale. As the shaft 231 rotates clockwise, one end of the movable color sheet 22 comes out of the first opening 212 and covers the dial 21. When the shaft 231 rotates counterclockwise, the movable color sheet 22 returns to the bottom of the dial 21. The movable color sheet 22 can be a segment of an arc-shaped color sheet or a whole annular color sheet. Figure 6 The movable color sheet 22 shown is a circular ring color sheet. When the movable color sheet 22 is a circular ring color sheet, a second opening 221 is provided on the movable color sheet 22, and one end of the movable color sheet 22 located at the second opening 221 can pass through or return from the first opening 212, while the other end of the movable color sheet 22 is at the bottom of the dial 21.
[0052] like Figure 3 As shown, the bottom surface of the first groove 113 of this embodiment is a spirally ascending height gradient surface, so that the bottom surface of the first groove 113 forms a step 118, one side of the first opening 212 is located at the high part of the step 118, and the other side is located at the low part of the step 118. The step 118 facilitates the movable color sheet 22 to pass through and return smoothly from the first opening 212. The low part of the step 118 is on the same plane as the second groove 117, so that the dial 21 can fit on the bottom of the second groove 117, and the dial 21 is prevented from interfering with the movable color sheet 22 passing through the first rotating opening 212. A convex surface 119 is provided on the bottom of the second groove 117 near the step 118, and the convex surface 119 props up the movable color sheet 22, so that the movable color sheet 22 can pass through the first opening 212 smoothly onto the dial 21.
[0053] The utility model replaces the pointer with an active color piece 22, rotates the shaft 231 to set the countdown time, and the dial 21 rotates at the movement 23 along with the shaft 231. During the timing process, the color piece guide foot cooperates with the guide foot of the dial, and the area of the active color piece 22 on the dial 21 will gradually decrease until the timing ends. The visualized visual effect is particularly suitable for children and is used to cultivate their sense of time.
[0054] In another specific embodiment of the utility model, the timing module 2 further includes a transfer shaft 27 and a knob 28, one end of the transfer shaft 27 is connected to the rotating shaft 231, and the other end is connected to the knob 28; a circle of limiting ring 271 is provided on the transfer shaft 27, and a fourth hole 222 is provided on the movable color sheet 22, the outer diameter of the limiting ring 271 is larger than the diameter of the fourth hole 222, and the movable color sheet 22 is clamped between the limiting ring 271 and the knob 28. In this way, the connection between the movable color sheet 22 and the rotating shaft 231 is realized, the disassembly and assembly is increased, and the parts are easily replaced, and the movable color sheet of different colors can be replaced according to personal preference.
[0055] In another specific embodiment of the utility model, the timing module further includes a circuit board 24, a battery 25 and a buzzer. The circuit board 24 of this embodiment is a PCBA board. The battery 25 and the circuit board 24 are connected by setting a battery conductive sheet 26. The circuit board 24 is connected to the movement 23 and the buzzer, and the buzzer is used to prompt the end of the time announcement. In this embodiment, the rotation countdown of the color chip can be realized by rotating the movement 23. When the countdown ends, the feedback signal of the circuit board 24 controls the buzzer to emit a sound to prompt the end of the time announcement.
[0056] The present embodiment is also provided with a pause button 6, which is connected to the circuit board 24 for stopping the countdown at any time. When the countdown ends, the buzzer will sound, and by pressing the pause button again, the buzzer stops making a sound.
[0057] In another embodiment of the utility model, a prompt light can be set. When the countdown ends, there is a light prompt (flashing or long on), and the pause button 6 is pressed again to turn off the light.
[0058] In this embodiment, a battery slot is provided on the bottom shell 12 for accommodating the battery 25 , and a detachable battery cover 123 is installed on the battery slot to facilitate replacement of the battery 25 .
[0059] In a specific embodiment of the utility model, the rotating assembly includes an end cover 3, one end of the end cover 3 is open and the other end is closed, and a first hole 31 is provided at the closed end of the end cover for passing the rotating shaft 231 in the timing module 2, and the first hole 31 corresponds to the position of the timing display window, so that the timing display window is exposed, that is, the first hole 31 is coaxial with the first groove 113 on the face shell 11; a limit block 32 is provided at the edge of the open end of the end cover 3, specifically, the limit block 32 is provided on the inner side wall of the end cover 3; the end cover 3 is coaxially sleeved on the face shell 1, and the limit block 32 cooperates with the step surface 112 to realize the axial positioning of the end cover 3, and the end cover 3 can rotate around the central circumference of the shell 1.
[0060] As another embodiment of the present invention, a guide groove 114 is provided on the side of the housing 11. Figure 3 As shown, one end of the guide groove 114 passes through the end of the housing 1, and the other end does not pass through the step surface 112. The extension direction of the guide groove 114 is perpendicular to the step surface 112. The position of the guide groove 114 corresponds to the position of the limit block 32. A plurality of limit blocks 32 are sequentially arranged along the circumference of the end cover 3. Accordingly, the number of the guide grooves 114 corresponds to the number of the limit blocks 32. By providing a small section of the guide groove 114, it is convenient for the limit block 32 to be smoothly inserted into the step surface 112 when the end cover 3 is installed.
[0061] As another embodiment of the utility model, the contact end surfaces of the face shell 11 and the end cover 3 are roughened. Specifically: a limiting protrusion A is provided on the end surface of the face shell 11 at one end of the end cover 3, and a limiting groove (not shown in the figure) is provided on the inner end surface of the end cover 3. The length direction of the limiting groove is along the radial direction of the end cover 3, and the depth of the limiting groove is about 1 mm. There are multiple limiting grooves, and the multiple limiting grooves are distributed in sequence along the circumference of the end cover 3 with the axis of the end cover 3 as the center of the circle, so that a circle of limiting grooves is formed on the end cover 3. When the end cover 3 is rotated, the limiting protrusion A passes through the limiting groove on the inner end surface of the end cover 3. When the end cover 3 is not rotated, the limiting groove and the limiting protrusion A cooperate to make the end cover 3 stay at the desired position, which plays a role in limiting the end cover 3 and avoiding the problem that the end cover 3 is unstable due to the smooth contact surface between the end cover 3 and the face shell 11.
[0062] In this embodiment, the edge of the limiting groove is in an arc shape, so that the edge of the limiting groove is smooth, ensuring that the limiting protrusion A moves smoothly on the limiting groove.
[0063] In this embodiment, a plurality of limiting protrusions A, for example four, are provided along the circumference of the surface shell 11 , and the four limiting protrusions A are evenly spaced and distributed on the surface shell 11 .
[0064] The limiting protrusion A can be compressed and rebounded along the axial direction of the face shell (i.e., the direction perpendicular to the limiting groove), so that the limiting protrusion A moves more smoothly along the limiting groove. Specifically: a strip plate B is formed on the end face of the face shell 11, one end of the strip plate B is connected to the face shell 11, and the other end is free. The limiting protrusion A is arranged on the free end of the strip plate B. In this example, a U-shaped groove is processed on the end face of the face shell 11, and the U-shaped groove passes through the wall thickness of the end face of the face shell 11, thereby forming a strip plate B with one end connected to the face shell 11 and the other end being free.
[0065] In another embodiment of the utility model, a plurality of adjustment slots may be provided on the side wall of the end cover 3 , and the slot directions of the adjustment slots are perpendicular to the end surface of the end cover 3 , so that the end cover 3 can be sequentially clamped on the housing 1 .

The knowledge content piece 4 is supported by a circle of the outer edge 33, and the knowledge content piece 4 is clamped by the cooperation of the protrusion and the card slot.
[0067] In another embodiment of the utility model, a transparent sheet 5 is provided on the first hole 31 to protect the timing module 2. A through hole 51 is provided at the center of the transparent sheet 5 for the rotating shaft 231 or the adapter shaft 27 to pass through.
[0068] In a specific embodiment of the present invention, the knowledge content piece 4 is arranged in the area around the first hole 31 of the end cover 3. The knowledge content piece 4 is annular, and the inner diameter of the annular ring matches the diameter of the first hole 31 to prevent the knowledge content piece 4 from blocking the timing display window.
[0069] The utility model arranges a rotating component on the timer body, and arranges a knowledge content sheet 4 on the rotating component, on which some knowledge contents (such as the twenty-four solar terms) are posted, so that the user can learn different knowledge in addition to using it as a timer; generally, a plurality of pieces of knowledge contents are distributed in sequence along the circumference of the rotating component with the center of the rotating component as the center of a circle, with the top of the text facing the center of the circle and the bottom of the text away from the center of the circle, which is inconvenient for the user to read; the direction of the knowledge contents can be adjusted by rotating the rotating component, so that the user can read more conveniently.
[0070] In another embodiment of the present invention, a support base may be provided at the bottom of the housing 1 (ie, the bottom shell 12 ) for stably placing the entire multifunctional timing device on a desktop or tabletop.
[0071] When the shell 1 is a cylindrical shell, a plane is set on one side of the bottom shell 12 away from the end cover 3, and the plane forms a certain angle with the axis of the bottom shell 12. When the multi-functional timing device is placed on the table, one end of the end cover 3 is slightly tilted, which is convenient for rotating the end cover 3 and also easy to watch from a viewing angle.
