[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way serves as any limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 2 As shown, an embodiment of the present invention provides a laboratory voice timing device, including a shell structure 10, a power supply 20, a voice control switch 30, a timer 40, an alarm 50 and a voice receiving microphone 60. The power supply 20, the voice control switch 30, the timer 40, the alarm 50 and the voice receiving microphone 60 are all installed on the shell structure 10. The power supply 20 at least supplies power to the timer 40 and the alarm 50. The voice receiving microphone 60 is used to receive voice commands and transmit them to the voice control switch 30. The voice control switch 30 controls the timer 40 to start timing according to the voice commands. After the timing of the timer 40 reaches the set time, the alarm 50 issues an alarm message.

[0033] In this embodiment, when the operator needs to perform a timing operation, they issue a pre-set voice command, such as "start timing." Upon receiving the voice command, the voice control switch 30 automatically controls the timer 40 to start timing. When the timer 40 reaches the set time, the alarm 50 issues an alarm message to alert the operator. This allows the operator to time the time through voice control, reducing or eliminating manual operation, thus avoiding the inconvenience of operating a clock or mobile phone while wearing gloves in the laboratory.

[0034] In practical applications, this design significantly reduces interference during experiments, improving the reliability of experimental data and the safety of experimental operations. For example, when conducting a chemical reaction experiment, the experimenter can focus on observing the reaction process without being distracted by operating the timer. This avoids hand contamination or interruption of reaction observation caused by operating the timer, ensuring the continuity and accuracy of the experiment.

[0035] Among them, power supply 20 is a 24V DC power supply. The setting of power supply 20 can provide a safer and more stable power supply for the equipment, and is also easy to maintain. This power supply selection is particularly important when handling sensitive experimental materials, such as in electron microscope laboratories and biotechnology laboratories, where electromagnetic interference may affect experimental results. The use of a 24V DC power supply effectively avoids this problem. At the same time, its low voltage characteristics also reduce the risk of electric shock, providing a safer experimental environment for experimenters.

[0036] like Figure 2 Timer 40 is a time relay, and alarm 50 is a flashing buzzer. Through the coordinated operation of timer 40 and alarm 50, when a task's timer expires, a signal is transmitted from timer 40 to alarm 50. This setting automatically sounds a reminder when the current task's timer expires, preventing those who lose track of time and thus affect the accuracy of analysis results. If multiple test tasks are arranged consecutively, this setting can also serve as a reminder for the next task, saving time and improving work efficiency.

[0037] Specifically, the laboratory voice timing device further includes a self-locking switch 70, which is used to control the electrical connection or disconnection between the power supply 20 and the timer 40. The self-locking switch 70 has an on / off indicator light. In this embodiment, the self-locking switch 70 is directly connected to the power supply 20 and the timer 40. The positive terminal of the timer 40 is connected to the positive terminal of the power supply 20 through the self-locking switch 70. The self-locking switch 70 is in a normally closed state. In this state, the power supply 20 can normally power the timer 40, and the timer 40 operates normally. When the current working time of the timer 40 is reached, the self-locking switch 70 is opened, and the timer 40 stops working, thereby ensuring the accuracy of the current working time. The self-locking switch 70 also has an on / off indicator light. The presence of the on / off indicator light allows staff to better identify the working status of the laboratory voice timing device, avoid misoperation that may cause the current working time to fail, and improve work efficiency.

[0038] like Figure 1 As shown, the laboratory voice timing device also includes a reset switch 80, which is electrically connected to the timer 40 and is used to reset the timer 40 to zero. In this embodiment, when the timer 40 reaches its current operating time, a signal is transmitted to the reset switch 80, which then resets the timer 40 to zero. If multiple test tasks are arranged consecutively, the timer 40 can be reset promptly to ensure that the timer 40 can proceed to the next task in a timely manner, reducing time waste.

[0039] Furthermore, the laboratory voice timing device includes a heat dissipation fan mounted on the housing structure 10 and electrically connected to the power supply 20. The heat dissipation fan is mounted on the back panel of the housing structure 10 and is installed in a hole in the back panel of the housing structure 10 to facilitate heat dissipation from the power supply 20 and other components, thereby ensuring stable operation of the power supply 20 and other components and extending their service life.

[0040] Furthermore, a power supply 20, a voice control switch 30, a timer 40, an alarm 50, and a voice receiving microphone 60 constitute a timing unit. The laboratory voice timing device includes multiple timing units, wherein different timing units have different voice instructions. The voice receiving microphone in the timing unit can pre-set the command for starting and ending the project. During operation, it can receive the staff's command instructions and turn on or off the voice control switch 30 according to different commands, reducing some unnecessary steps and cumbersome operations. In this embodiment, there are multiple timing units, which can perform timing operations on multiple tasks simultaneously, and different times can be set for the timers 40 in different timing units, realizing multi-channel timing without interfering with each other, effectively improving work efficiency.

[0041] The laboratory voice timing device also includes multiple rubber feet 90 distributed along the bottom wall of the housing structure 10. These rubber feet increase friction, preventing the housing structure 10 from sliding or shaking during use, thereby improving the stability of the device. This arrangement also reduces vibration transmission between the housing structure 10 and the surface on which it is placed, thereby reducing noise generated by vibration. Furthermore, a certain gap is maintained between the bottom of the housing structure 10 and the surface on which it is placed, facilitating cleaning and maintenance of the bottom of the housing and preventing the accumulation of dust and debris.

[0042] Specifically, the housing structure 10 is a cubic structure comprising a front wall and a rear wall disposed opposite each other. The voice control switch 30, timer 40, alarm 50, and voice receiving microphone 60 are all mounted on the front wall, while the power supply 20 is mounted on the rear wall. This arrangement provides a simple structure and a large internal space, facilitating the arrangement of various components.

[0043] Among them, the voice control switch 30, timer 40, alarm 50 and voice receiving microphone 60 are all installed on the front side wall, which is convenient for personnel to operate and easy to receive voice commands issued by personnel, and personnel can check the time displayed on the timer 40 or set the time.

[0044] The side walls of the housing structure 10 are made of acrylic or aluminum-plastic panels, and the rear side wall is detachably mounted via magnetic attraction. Using acrylic or aluminum-plastic panels for the side walls of the housing structure 10 reduces the weight of the entire device, and the rear side wall is magnetically mounted to allow for detachable assembly and disassembly, facilitating subsequent mobile use and adapting to a variety of work scenarios.

[0045] The working principle of this solution is as follows: the staff sets the start and end commands for the voice receiving microphone 60 in advance. When using the device, the staff speaks the preset start command, and the voice receiving microphone 60 turns on the voice control switch 30 after receiving the command. After the voice control switch 30 is turned on, the power supply 20 starts to supply power. Since the self-locking switch 70 is in a normally closed state, the power supply 20 can directly supply power to the timer 40, and the timer starts timing, which can reduce some unnecessary steps and tedious operations; when the timing time is reached, the timer transmits a signal to the self-locking switch 70, the alarm 50 and the reset switch 80, the self-locking switch 70 is turned on, the timer 40 stops timing, the alarm 50 automatically sounds a reminder, and the reset switch 80 resets the timer 40, so as to ensure the accuracy of the current working time, enter the next task in time, reduce time waste and improve work efficiency.

[0046] Furthermore, the cooling fan design ensures stable operation of the power supply 20, extending its service life. The rubber foot pads prevent the housing structure 10 from sliding or shaking during use, improving device stability. The magnetic design facilitates subsequent mobility and is suitable for a variety of work scenarios.

[0047] This laboratory voice timing device uses voice control to realize timing operations, which greatly improves the convenience and safety of laboratory operations and avoids the potential risks brought by manual setting of timers by experimenters during operation. At the same time, the design of multiple independent timing units can meet the needs of the laboratory to conduct multiple experiments at the same time, thereby improving experimental efficiency. The special design of the shell structure and the detachable rear side wall facilitate the maintenance and upgrade of the device, ensuring long-term stable working performance. In addition, the modular design of the device allows it to be customized according to the specific needs of the laboratory, such as adding more timing units, adjusting the alarm method, etc., so as to better adapt to different types of experimental operations. The portability and scalability of the device make it not only suitable for fixed laboratories, but also play an important role in scenarios such as mobile laboratories and field scientific research, providing researchers with more flexible and efficient time management tools.
