[0012] Furthermore, the voice control module also includes a preprocessing module.

[0013] Beneficial effects:

[0014] 1. Connect the power cord to the external power socket for power supply, heat through the heating component, protect through the protective cage during heating, control the temperature through the knob switch, when the fire is roasting, the reflective film monitors the temperature of the heating component, as the temperature rises, the reflective film expands, and the bottom of the reflective film will press the switch 10 to stop the heating component from heating to avoid fire caused by high temperature.

[0015] 2. When heating, the carbon crystal heating plate is heated, and the carbon crystal heating plate radiates the heat upward, and then radiates downward through the reflective bowl, and conducts the heat through the radiation tube to radiate the heat to the periphery.

[0016] 3. Through the setting of infrared sensors, when people leave the stove, the infrared sensor detects that the people are away. When the distance reaches the set value, the single-chip microcomputer module receives the relevant data and controls the carbon crystal heating plate through the built-in control program of the single-chip microcomputer, so that the carbon crystal heating plate is powered off and stops heating, which can effectively avoid the occurrence of fires caused by people forgetting to use the stove.

[0017] 4. During intelligent interaction, the user wakes up by saying "small stove, small stove" and after the awakening is completed, the machine responds: the speaker plays "yes", and the user inputs the command: "turn on the stove", and the command is confirmed: the speaker plays "whether to turn on the stove", and the user confirms the command by saying "yes or confirm a certain word". After receiving the confirmation command, the command is executed, and the command signal is converted into an execution signal recognizable by the single-chip microcomputer module through the output control module, and the carbon crystal heating plate is turned on through the single-chip microcomputer module.

[0018] 5. Compared with the prior art, the present invention does not need to set a temperature sensor. By filling the cavity in the radiation film with heat-expanding gas, when the temperature is too high, the thermal expansion change of the reflective film supports the push switch to be pressed, so that the heating component stops heating. As the temperature drops, the reflective film contracts, so that the push switch returns to its original state, and the heating component is reheated to avoid fires caused by long-term high temperatures. In addition, through the setting of infrared sensors and single-chip microcomputer modules, when people are away from the stove, the heating component stops heating to avoid fires caused by forgetting to turn off the stove. This is safer and voice control can be performed through the voice control module.

DETAILED DESCRIPTION

[0028] Please refer to Figures 1 to 7 ;

[0029] This embodiment provides a safe stove for voice control. Figure 1 ,and Figure 6 , comprising a base 1, an integrated circuit board 11 is arranged inside the base 1, a knob switch 8 and a power cord 9 are arranged on the outer wall of the base 1, a reflective film 2 that expands due to heat is arranged on the top of the base 1, a push switch 10 is arranged below the reflective film 2, a heating component 3 is arranged in the middle of the upper surface of the reflective film 2, and a protective cage 4 fixed to the top edge of the base 1 is arranged on the periphery of the heating component 3;

[0030] In a specific implementation, the power cord 9 is connected to an external power socket to supply power, and heating is performed through the heating component 3. During heating, protection is provided by the protective cage 4, and the temperature is controlled by the knob switch 8. When a fire is being heated, the reflective film 2 monitors the temperature of the heating component 3. As the temperature rises, the reflective film 2 expands, and the bottom of the reflective film 2 presses the switch 10 to stop the heating of the heating component 3 to avoid a fire caused by high temperature.

[0031] For further reference, Figure 4 and Figure 5 The reflective film 2 includes an upper arc surface 201 that is raised upward and is set in a circular arc shape. The lower surface edge of the upper arc surface 201 is integrally connected with a lower arc surface 202 that is raised downward and is in a circular arc shape. A cavity formed between the upper arc surface 201 and the lower arc surface 202 is provided with a heat expansion gas. The edges of the upper arc surface 201 and the lower arc surface 202 are connected to the top edge of the base 1. A sleeve platform 202 is provided in the middle of the upper surface of the upper arc surface 201. The sleeve platform 202 is used to fix the heating component 3. A vertical upward support rod 12 is provided in the middle of the inner part of the base 1. A press switch 10 is provided on the top of the support rod 12. The press switch 10 is close to the lower surface of the lower arc surface 202.

[0032] In a specific implementation, when the power is automatically cut off by the thermal expansion change of the reflective film 2, the thermal expansion gas inside the cavity expands, causing the upper arc surface 201 to expand upward and the lower arc surface 202 to expand downward. When the temperature reaches the critical value of the safe temperature, the lower surface of the lower arc surface 202 supports the push switch 10, so that the push switch 10 is pressed, the heating component 3 is powered off and the heating stops. The heating component 3 can heat within the safe temperature, which is safer.

[0033] When the temperature drops, the heat-expanding gas expands and contracts, causing the upper arc surface 201 and the lower arc surface 202 to shrink, so that the push switch 10 is released, and the heating component 3 is powered on to heat;

[0034] At the same time, when the upper arc surface 201 expands upward, the arc radius of the surface of the upper arc surface 201 becomes larger, so that the heat can be reflected in a wider direction through the upper arc surface 201.

[0035] Preferably, the thermal expansion gas is nitrogen;

[0036] In a specific implementation, the nitrogen is heated and expanded;

[0037] In the absence of a temperature sensor, when the temperature is too high, the push switch 10 can be pressed by the expansion of the reflective film 2 to cut off the power to the heating component 3.

[0038] For further reference, Figure 5 and Figure 6 The heating assembly 3 includes a radiation tube 301 sleeved on the outer periphery of the sleeve platform 202, the outer wall of the radiation tube 301 is provided with a plurality of through holes, the bottom of the radiation tube 301 is provided with a carbon crystal heating plate 303 located on the top of the sleeve platform 202, and the top of the radiation tube 301 is provided with a reflection bowl 302, the reflection bowl 302 is convex, and the carbon crystal heating plate 303 is concave;

[0039] In specific implementation, when heating is performed, the carbon crystal heating plate 303 is heated, and the carbon crystal heating plate 303 radiates heat upward, and then radiates heat downward through the reflection bowl 302, and conducts the heat through the radiation tube 301 to radiate the heat to the periphery.

[0040] For further reference, Figure 1 and Figure 6 The protective cage 4 is made of at least four annular cross bars 401 and a plurality of vertical bars 402 intersecting and welding, the vertical bars 402 are arranged in an L shape, and a handle 403 is provided in the middle of the top of the plurality of vertical bars 402;

[0041] During specific implementation, the entire device is carried by means of the handle 403 .

[0042] Furthermore, the diameter of the crossbar 401 is greater than the diameter of the vertical bar 402. The base 1 includes a circular shell 101. The bottom of the shell 101 is clamped with a bottom plate 102. The top of the shell 101 is provided with a sleeve groove 103. The sleeve groove 103 is clamped with the crossbar 401 at the bottom.

[0043] In a specific implementation, when the protection cage 4 is connected to the housing 101 , the cross bar 401 at the bottom is inserted into the socket groove 103 to complete the installation of the protection cage 4 , making the installation of the protection cage 4 more convenient.

[0044] For further reference, Figure 7 The integrated circuit board 11 is provided with a single-chip computer module 112, and at least eight infrared sensors 5 are evenly arranged on the outer wall of the housing 101. The single-chip computer module 112 has a built-in control program for controlling the operation of the carbon crystal heating plate 303 based on the monitoring data of the infrared sensors 5;

[0045] In the specific implementation, through the setting of infrared sensor 5, when a person leaves the stove, the infrared sensor 5 detects that the person is moving away. When the distance reaches the set value, the single-chip computer module 112 receives relevant data, and controls the carbon crystal heating plate 303 through the built-in control program of the single-chip computer 112, so that the carbon crystal heating plate 303 is powered off and stops heating, which can effectively avoid the occurrence of fires caused by people forgetting to use the stove.

[0046] For further reference, Figure 1 and Figure 7 , a voice control module 111 is also provided on the integrated circuit board 11, and at least one speaker 6 and at least one microphone 7 are provided on the outer wall of the housing 101;

[0047] In specific implementation, when voice control is performed;

[0048] The user controls by voice, voice wake-up: small stove, small stove, the voice control module 111 receives the relevant voice information, wakes up the voice control module 111, and after waking up the voice control module 111, controls heating and shutting down by voice, heating: turning on the stove, shutting down: turning off the stove;

[0049] When performing voice control, the microphone 7 inputs the voice and performs human-computer interaction with the voice control module 111 through the speaker 6.

[0050] For further reference, Figure 7 , the voice control module 111 includes a voice collection module 111, a voice recognition module 1112, an intelligent interaction module 1113 and an output control module 1114;

After the recognition is completed, the intelligent interaction module 1113 communicates with the voice control module 111, and the voice information of the voice intelligent interaction module 1113 is played through the speaker 6;

[0052] During intelligent interaction, the user wakes up by voice "small stove, small stove". After the wake-up is completed, the machine feedback: the speaker 6 plays "yes", the user inputs the command: "turn on the stove", the command confirmation: the speaker 6 plays "whether to turn on the stove", the user confirms the command, says "yes or confirms a kind of affirmative words", after receiving the confirmation command, the command is executed, and the command signal is converted into an execution signal recognizable by the single-chip module through the output control module, and the carbon crystal heating plate 303 is turned on through the single-chip module 12;

[0053] Among them, the control priority is that the control of the press switch 10 is greater than the control of the voice control module 111, which is greater than the control of the infrared sensor 5 and which is greater than the control of the knob switch 8.

[0054] For further reference, Figure 7 , the voice control module 111 also includes a pre-processing module 113;
