Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. Those skilled in the art can fully understand the present invention without the description of these details.

[0023] It should be noted that when two elements are referred to as being "fixedly connected" or "fixedly connected", the two elements may be directly connected or there may be an intermediate element. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "horizontal", "upper", "lower" and similar expressions used herein are for illustrative purposes only.

[0024] like Figure 1 A voice recognition controlled gas experimental device is shown, which includes a reaction container 1, a balloon 2, a hose 3 and a candle 4. The experimental device also includes a delivery container 5, a delivery device 6 for controlling the delivery of the delivery container 5, a three-way pipe 7, an observation box 8 and a voice recognition system. The reaction container 1 is a split type, including an upper end 10 and a lower end 11, and the upper end 10 and the lower end 11 are sealed and connected.

[0025] The delivery container 5 is arranged on the inner side of the lower end portion 11 of the reaction container 1, the delivery device 6 is connected to the delivery container 5, the side wall of the delivery container 5 is a magnetic material, the delivery device 6 includes a traction rope 9 and an electromagnet 16, one end of the traction rope 9 is connected to the bottom of the delivery container 5, and the other end is fixedly arranged on the reaction container 1, the electromagnet 16 is arranged on the outer wall of the reaction container 1, and is attracted to the delivery device 6 when powered on, and the voice recognition system controls the power on and off of the electromagnet 16 through instruction 1, the end of the traction rope 9 not connected to the bottom of the delivery container 5 is arranged on the outer side of the reaction container 1, the other end of the traction rope 9 is arranged on the outer side of the reaction container 1, and the traction rope 9 is fixed by setting a hook on the outer side of the reaction container 1, so as to facilitate the recovery and placement of the delivery container 5, and the delivery container 5 is a cup-shaped opening which is arranged upward in the reaction container 1, and is adsorbed and connected with the energized electromagnet 16 through the magnetic material of the side wall. When the electromagnet 16 is powered off by instruction 1, the delivery container 5 falls freely, and the traction rope 9 at the bottom causes the delivery container 5 to overturn, and the baking soda in the delivery container 5 falls into the white vinegar in the reaction container 1 to react. This design changes the original baking soda that needs to be manually introduced from the balloon 2 into a voice-controlled mode through the electromagnet 16 and the magnetic material, which can better control the progress of the reaction. At the same time, the traction rope 9 can prevent the delivery container 5 from falling to the bottom of the reaction container 1, which can make it more convenient to recycle the delivery container 5 and facilitate multiple recycling. Compared with the original experimental method, the reaction process can be controlled more accurately.

[0026] The three-way pipe 7 includes a pipe mouth 12, a pipe mouth 2 13 and a pipe mouth 3 14. The pipe mouth 12 is connected to the balloon 2, the pipe mouth 2 13 is connected to the hose 3, and the pipe mouth 3 14 is connected to the reaction container 1. The end of the hose 3 not connected to the three-way pipe 7 is arranged in an observation box 8. The observation box 8 is a transparent square box with a candle holder 17 arranged inside. The candle 4 is arranged on the candle holder 17. There are 5 candle holders 17, which are arranged in order from high to low. The height of the candle holder 17 is set from high to low. During the experiment, the candle 4 is lit and the hose 3 is set. One end is placed in the observation box 8, the nozzle is set at the bottom of the observation box 8, and the shortest candle 4 is placed at the end away from the nozzle of the hose 3. This arrangement prevents the turbulence generated after the gas enters the observation box 8 from affecting the candle flame of the candle 4. After the gas enters the observation box 8, the candles 4 will be extinguished in sequence from low to high. The nature of the gas can be further identified by observing the state of the candles 4. The upper part of the observation box 8 is an open side panel as a movable panel. The side panels of the observation box 8 are set as movable panels, which is convenient for installing and replacing the candles 4 before each experiment.

[0027] The hose 3 is provided with a control device for controlling the opening and closing of the hose 3. The control device is a solenoid valve, which is arranged in the middle of the hose 3. The voice recognition system controls the opening and closing of the solenoid valve through instruction 2. When baking soda and white vinegar react to produce gas, it is necessary to observe the generation of gas first, so that the balloon 2 connected to the three-way pipe 7 expands. In order to prevent the gas from directly entering the observation box 8 from the hose 3 after the gas is generated, a solenoid valve is arranged in the middle of the hose 3. At the beginning of the experiment, the solenoid valve is closed, and the generated gas expands the balloon 2. When it is desired to further identify the properties of the gas, instruction 2 is used to open the solenoid valve, and the gas flows into the observation box 8, so as to further analyze the properties of the gas.

[0028] The reaction vessel 1 is also provided with an infrared temperature sensor 18 and a display screen 19. The infrared temperature sensor 18 is connected to the display screen 19 and absorbs heat during the experiment. In order to more intuitively observe the temperature change of the reaction vessel 1 during the experiment, the infrared temperature sensor 18 is provided on the reaction vessel 1. The temperature measured by the infrared temperature sensor 18 can be observed through the display screen 19 to observe the reaction progress.

[0029] The observation box 8 is also provided with a carbon dioxide detection module 20, a display screen and a reminder device 15. The carbon dioxide concentration detection module is on the lower side of the highest candle 4, and the display screen and the reminder device 15 are on the top side of the observation box 8. When the carbon dioxide concentration is greater than 600ppm, the reminder device 15 will alarm. The normal air concentration is less than 500ppm. The carbon dioxide detection module 20 is set on the observation box 8, and the reminder device 15 will alarm when it is greater than the carbon dioxide concentration in the air.

[0030] During the experimental operation, the device is powered on, the infrared temperature sensor 18 senses the temperature in the reaction container 1 and displays it on the display screen 19, the carbon dioxide detection module 20 detects the carbon dioxide concentration in the observation box 8 and displays it on the display screen 21, and at this time, the electromagnet 16 is powered on with magnetic attraction, and the solenoid valve is in the valve closed state. The upper end 10 and the lower end 11 of the reaction container 1 are separated, baking soda is loaded into the delivery container 5, and white vinegar is poured into the lower end 11 of the reaction container 1, and the magnetic material on the side wall of the reaction container 1 is adsorbed and installed with the electromagnet 16, ensuring that the other end of the traction rope 9 is placed outside the reaction container 1 and fixed, and then the upper end 10 and the lower end 11 of the reaction container 1 are installed, the side panel of the observation box 8 is taken out and the candle 4 is placed, and the side panel is installed to start the experiment.

[0031] The voice recognition system issues a command to cut off the power to the electromagnet 16, and the delivery container 5 freely falls after losing the magnetic attraction. Due to the action of the bottom traction rope 9, the delivery container 5 overturns, and the baking soda falls into the white vinegar. At this time, the baking soda reacts with the white vinegar to produce gas. Since the solenoid valve on the hose 3 is in a closed state, the balloon 2 connected to the three-way pipe 7 will expand, and the temperature change will be displayed on the display screen 19. After it is obvious that the expansion of the balloon 2 has stopped, the voice recognition system issues a command 2, the solenoid valve opens, and the carbon dioxide gas enters the observation box 8 from the hose 3. The balloon 2 gradually becomes smaller, and the degree of the carbon dioxide concentration display screen increases. The reminder device 15 alarms, and it can be observed that the candles 4 are extinguished from low to high.

[0032] By setting up a delivery container 5, a delivery device 6 and a voice recognition system, the progress of the experiment can be controlled by voice to prevent errors and failures in the experiment caused by human operation, thereby improving the success rate of the experiment and increasing the interest of the experiment. By setting up a traction rope 9 and setting the side panels of the observation box 8 as movable panels, it is convenient to conduct experiments repeatedly and repeat the experiment. By setting up an infrared temperature sensor 18 and a carbon dioxide detection module 20, the overall process of the experiment can be felt in an intuitive way through detection of numerical values, which has a more intuitive effect.

[0033] The above describes the implementation mode of the utility model in detail in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation mode. For ordinary technicians in this field, several modifications and improvements can be made without departing from the present invention, and these should also be regarded as belonging to the protection scope of the present utility model.
