Description

Technical Field

[0001] The utility model relates to the technical field of timing devices, in particular to a dual-display timer. Background Art

[0002] A timer is designed based on timing to achieve a reminder when the countdown time arrives. For example, for a preset time, when a certain time is reached, the timer will emit a ringing sound to remind the timing person that the preset time has arrived. Timers are widely used due to their small size, convenient timing operation, and strong practicability.

[0003] However, the existing timer products have a single form. The timers in the related technologies include mechanical ones and electronic button ones. The mechanical ones have an intuitive and obvious display, but the internal design of the timer includes structures such as mechanical hairsprings and gears, which have problems of complex cooperation and large errors. Although the electronic ones are convenient to operate, the display is not intuitive and obvious enough. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a dual-display timer that combines the advantages of mechanical and electronic button types.

[0005] To solve the above technical problem, the technical solution adopted by the utility model is to provide a dual-display timer, which includes a housing, a control circuit arranged in the housing, a liquid crystal display and a mechanical timing pointer display component arranged on the surface of the housing; the mechanical timing pointer display component includes a scale panel, a timing pointer and a stepping motor; the timing pointer is driven by the stepping motor to rotate on the surface of the scale panel;

[0006] The liquid crystal timing display, the stepping motor and the control circuit are electrically connected, and the control circuit controls the time data displayed on the liquid crystal timing display and the mechanical timing pointer to be the same. The timing range of the scale panel is 0 - 180 minutes.

[0007] The beneficial effect of the utility model lies in that: the dual-display timer of the utility model uses a stepping motor to replace the conventional quartz movement to provide power. The stepping motor is simpler, more reliable and lower in cost than the mechanical movement. The control circuit of the utility model is connected to the liquid crystal display to calculate and display the time on the liquid crystal display through a chip. Compared with the mechanical pointer countdown, the display is more accurate, the error is smaller, and the scale range setting is more free (the traditional mechanical timer generally has preset scales such as 60 minutes, and the timing range is not easy to change. The stepping motor used in the utility model can conveniently set any scale range time for countdown). Brief Description of the Drawings

[0012] To describe in detail the technical content, achieved purpose and effects of the present utility model, the following is described in conjunction with the implementation manners and with reference to the drawings.

[0013] Please refer to Figure 1 and Figure 2 As shown, the present utility model provides a dual-display timer, including a housing 1, a control circuit disposed inside the housing 1, a liquid crystal display 2 and a mechanical timing pointer 4 display assembly disposed on the surface of the housing 1; the mechanical timing pointer 4 display assembly includes a scale panel 3, a timing pointer 4 and a stepper motor 5; the timing pointer 4 is driven by the stepper motor 5 to rotate on the surface of the scale panel 3;

[0014] The liquid crystal timing display, the stepper motor 5 and the control circuit are electrically connected, the control circuit controls the time data displayed on the liquid crystal timing display and the mechanical timing pointer 4 to be the same, and the timing range of the scale panel is 0 - 180 minutes.

[0015] As described above, the beneficial effects of the present utility model are as follows: The dual-display timer of the present utility model uses a stepper motor to replace the conventional quartz movement to provide power. The stepper motor is simpler and more reliable than the mechanical movement and has a lower cost. The control circuit of the present utility model is connected to the liquid crystal display and calculates to display the time on the liquid crystal display through a chip. Compared with the mechanical pointer countdown, the display is more accurate, the error is smaller, and the scale range setting is more free (conventional mechanical timers generally have preset scales such as 60 minutes, and the timing range is not easy to change. The stepper motor used in the present utility model can conveniently set the time for any scale range for countdown). Compared with the traditional electronic countdown operation by button clicking, the operation feel of the timer in this application is different, and the countdown display is different. The present utility model combines the liquid crystal display and the scale panel, enabling the user to not only set the countdown length by rotating the timing pointer like a mechanical timer, but also simultaneously see the pointer countdown and the digital countdown on the scale panel and the liquid crystal display respectively, and can more intuitively feel the countdown. The present utility model satisfies the mechanical countdown operation requirements of customers while also having the advantages of electronic countdown.

[0016] Traditional mechanical timers generally have preset scales such as 60 minutes. It is not easy to change the timing range. The stepper motor used in this application can conveniently set the time for any scale range for countdown, such as a range of 0 - 180 minutes.

[0017] Further, in the above dual - display timer, the mechanical timing pointer display assembly further includes a knob, an encoder 6, and a roller 7;

[0018] The knob drives the roller and the pointer to rotate. The encoder rotates under the drive of the roller and outputs an electrical signal, thereby controlling the stepper motor to drive the timing pointer to rotate on the scale panel through a connecting member.

[0019] As described above, setting the knob can facilitate the user to adjust the position of the timing pointer.

[0020] Further, in the above dual - display timer, the front of the housing is circular. The entire front of the housing is the area set for the scale panel, and a liquid crystal display is provided at the center of the lower part of the scale panel.

[0021] As described above, the setting of the relative positions of the above liquid crystal display and the scale panel makes it more convenient for the user to view and is more intuitive.

[0022] Further, in the above dual - display timer, a buzzer is also connected to the control circuit.

[0023] Further, in the above dual - display timer, a buzzer is also connected to the control circuit.

[0024] Further, in the above dual - display timer, an indicator light is also connected to the control circuit.

[0025] As described above, an indicator light is provided on the control circuit for reminder when the set time is reached.

[0026] Further, in the above dual - display timer, a battery compartment for accommodating a battery is provided inside the housing.

[0027] As described above, setting the battery compartment allows for battery replacement, which is convenient for use.

[0028] Further, in the above dual - display timer, a lithium battery electrically connected to the control circuit is provided inside the housing.

[0029] As described above, setting the lithium battery allows for repeated charging and is convenient for use.

[0030] Further, in the above dual - display timer, a hanging ring is provided at the upper end of the housing 1.

[0031] As described above, setting the hanging ring facilitates the movement of the dual - display timer.

[0032] Furthermore, in the above dual-display timer, support legs are provided at the upper end of the housing 1.

[0033] As can be seen from the above description, the provision of support legs facilitates the stable placement of the dual-display timer.

[0034] Embodiment 1

[0035] Please refer to Figure 1 and Figure 2 , a dual-display timer, characterized by comprising a housing, a control circuit provided in the housing, a liquid crystal display and a mechanical timing pointer display component provided on the surface of the housing; the mechanical timing pointer display component includes a scale panel, a timing pointer and a stepping motor; the timing pointer is driven by the stepping motor to rotate on the surface of the scale panel; the timing range of the scale panel is 0-180 minutes.

[0036] The mechanical timing pointer display component further includes a knob, an encoder and a roller; the knob drives the roller and the pointer to rotate, and the encoder rotates under the drive of the roller to output an electrical signal, thereby controlling the stepping motor to drive the timing pointer to rotate on the scale panel through a connecting member.

[0037] The liquid crystal timing display, the stepping motor and the control circuit are electrically connected, and the control circuit controls the time data displayed on the liquid crystal timing display and the mechanical timing pointer to be the same.

[0038] The front surface of the housing is circular, the entire front surface of the housing is the area provided for the scale panel, and a liquid crystal display is provided at the center of the lower part of the scale panel.

[0039] The use of the above dual-display timer:

[0040] The user rotates the knob to set the timing pointer to the required moment. By rolling the roller, the encoder rotates to output an electrical signal. The control circuit is provided with a main control circuit which takes a main control IC or a single-chip microcomputer as the core. The program is set on the control circuit to control the adjustment of time. After receiving the electrical signal, the main control circuit displays the corresponding countdown time on the liquid crystal display and controls the countdown.

[0041] The timing pointer on the scale panel rotates to the scale line corresponding to the time on the liquid crystal display; when the roller is pressed down, the micro switch (button) is triggered, and the countdown starts to work. The main control circuit controls the stepping motor to drive the timing pointer to rotate on the scale panel; the values on the liquid crystal display and the timing pointer on the scale panel gradually decrease at the same time. When the timing returns to 0 o'clock, the light turns on or the bell rings.

[0042] The countdown of the dual-display timer of the present application is based on electronic timing, which is accurate and error-free compared to mechanical timing, and it is convenient to adjust the time range of the countdown. The mechanical countdown in the present application only uses the timing pointer to display the countdown time and does not affect the accurate operation of the countdown.
