[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. It should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] This utility model discloses an intelligent heater, which, in addition to normal functions, also features Braille buttons 109 and voice functionality, facilitating independent use by blind individuals. (See attached document.) Figure 1-8 A smart heater includes a heater body 100, a heating component 101 inside the heater body 100, the heating component 101 including a heating element 102 and an axial fan 103, an air outlet grille 104 at the front of the heater body 100, and an air inlet grille 105 at the rear of the heater body 100. The heating element 102 is mounted on a support frame 106, and the axial fan 103 is located behind the heating element 102. The axial fan 103 blows the air heated by the heating element 102 out through the air outlet grille 104 to form air convection for heating. The top of the heater body 100 has a Braille area 107 with several Braille characters 108. A button 109 is located below the axis of the Braille characters 108. The Braille characters 108 correspond to the functions of the button 109. This arrangement allows blind people to touch the button 109 by following the Braille characters 108 to understand their meaning, making it convenient for blind people to use the heater quickly.

[0030] like Figure 2A speaker 110 and a microphone 111 are mounted on the side of the support frame 106. A first PCB board 112 is also mounted on the support frame 106. The first PCB board 112 has a main control chip 200, a voice module 201, and a heating control circuit 202. The voice module 201 is connected to both the speaker 110 and the microphone 111. The voice module 201 takes the sound signal from the microphone 111 as input, converts it into an electrical signal, and outputs an electrical signal to the speaker 110, causing the speaker 110 to emit sound. The main control chip 200 communicates with the voice module 201 via a signal connection. The main control chip 200 receives signals from the button 109, data signals transmitted by the voice module 201, and other signals, and outputs signals to control the heating control circuit 202 to turn on or off. The heating control circuit 202 controls the heating component 101 to heat up by turning it on or off.

[0031] like Figure 6 The heating control circuit 202 includes two sets of heating controls: a first heating control 203 and a second heating control 204. The heating element 102 in the heater body 100 includes a first heating element 102 and a second heating element 102. The first heating element 102 and the second heating element 102 are arranged in parallel or side by side. The smart heater controls the heating of the first heating element 102 and the second heating element 102 through the first heating control 203 and the second heating control 204 respectively to achieve high-level heating, low-level heating and energy-saving heating. Specifically, one set of heating is low-level heating, two sets of heating is high-level heating, and two sets of heating together is energy-saving heating.

[0032] like Figure 6 The first heating control 203 includes a relay JDQ1, a transistor Q2, a diode D3, and a resistor R11. The collector of transistor Q2 is connected to the negative terminal of diode D3 and the coil contact 1 of relay JDQ1. The emitter of transistor Q2 is connected to ground. The base of transistor Q2 is connected to resistor R11 and main control chip 200. The main control chip 200 outputs a high-level signal to turn on transistor Q2. The coil contact 2 of relay JDQ1 is connected to a 12V DC voltage and the positive terminal of diode D3. The main contact 4 of relay JDQ1 is connected to the power supply line ACL. The main contact 3 of relay JDQ1 is connected to the first heating element 102. When transistor Q2 is turned on, relay JDQ1 is closed, thereby heating the first heating element 102. Similarly, the second heating control 204 includes a relay JDQ2, a transistor Q3, a diode D4, and a resistor R12. The circuit structure is the same as that of the first heating control 203. The relay JDQ2 is connected to the second heating element 102. When the transistor Q3 is turned on, the relay JDQ2 is closed, causing the second heating element 102 to heat up.

[0033] like Figure 6The main control chip 200 is a microcontroller IC with 16 pins. It inputs signals KEY1 and KEY2 from button 109, the NTC temperature control signal, and the IR infrared signal. It transmits signals to the voice module 201 via TX and RX signals. It outputs signals JDQ1 and JDQ2 to control the heating of the first and second heating elements 102, respectively, and outputs FAN to start the axial fan 103. Pins 1 and 2 of the microcontroller IC are used for inputting and outputting signals from the voice module 201; pin 3 is used to output a head-shaking signal; pin 4 is used to detect a tilting signal; pins 5 and 6 are used to control the heating output; pin 10 is used to detect the NTC temperature; pins 12 and 15 are used to detect the button 109 signal; pin 13 is used to output a buzzer signal; pin 14 controls the digital tube display; and pin 16 is used to receive the infrared signal.

[0034] When the main control chip 200 is in heating mode or temperature control energy-saving mode, it sends a heating signal, outputting a high level to the base of transistors Q3 and Q2 through pins 5 and 6, respectively turning on transistors Q3 and Q2. This closes relays JDQ1 and JDQ2, activating the heating element 102 circuit and initiating heating. Temperature control energy saving is achieved by intermittently outputting high levels to intermittently heat the heating element 102. For example, if the main control chip 200 receives a temperature control signal of 30 degrees Celsius, it detects the real-time temperature via NTC. If the current temperature reaches the set temperature T+2℃, relays JDQ1 and JDQ2 are turned off; if the current temperature is lower than the set temperature T-2℃, both relays JDQ1 and JDQ2 are turned on; if the current temperature is greater than or equal to T℃, only relay JDQ2 is turned on for heating. Temperature control is achieved by switching relays on and off.

[0035] like Figure 2 An NTC temperature sensor 113 is installed on the axial fan 103. The NTC temperature sensor 113 is connected to the NTC temperature control module 205 and transmits the collected temperature signal to the main control chip 200. The NTC temperature sensor 113 is installed on the axial fan 103 to collect the indoor air flowing in from the air inlet grille 105, so it can accurately reflect the indoor temperature. As shown in the figure, the NTC temperature control module 205 includes a resistor R13, a sampling resistor R14, a capacitor C2, and a port connected to the NTC temperature sensor 113. The 5V DC voltage, resistor R13, NTC temperature sensor 113 and ground point form a circuit. The resistance value of the NTC temperature sensor 113 gradually decreases as the temperature rises. The main control chip 200 inputs the analog signal collected by the sampling resistor R14 and obtains the corresponding temperature value after operation. Finally, the converted numerical signal is output to the digital tube for display.

[0036] like Figure 4A display panel 114 and an infrared connector 115 are provided above the air outlet mesh cover 104, such as... Figure 7 The infrared receiver is an infrared receiver head HW. The positive power supply pin of the infrared receiver head HW is connected to resistor R1 and 5V DC voltage, and the negative power supply pin of the infrared receiver head HW is grounded. An electrolytic capacitor EC2 is connected in parallel between the positive and negative power supply pins of the infrared receiver head HW. The output of the infrared receiver head HW is connected to the main control chip 200 to output the IR signal.

[0037] The infrared receiver head HW receives the infrared light waves sent by the remote control and converts them into corresponding electrical signals, which are then transmitted to pin 4 of the pin header and pin 16 of the connected microcontroller IC. The microcontroller IC's internal algorithm calculates the corresponding remote control code value and performs the corresponding operation.

[0038] like Figure 6 The voice module 201 is powered by a 5V DC power supply and is connected to the microphone 111 and speaker 110 via the MIC and SPK pin headers. The voice module 201 is connected to the main control chip 200 via pins 3 and 4 for data transmission. The microphone 111 is connected to the voice module 201 via the MIC pin header, which converts the sound signal into an electrical signal and inputs it to the voice module 201. The speaker 110 is connected to the voice module 201 via the SPK pin header, which converts the electrical signal into a sound signal.

[0039] The voice module 201 detects changes in the microphone 111 and converts them into digital signals. These signals are then transmitted to pin 1 of the main control chip 200 via pin 3. The main control chip 200 processes the signal internally and outputs the corresponding operation. Then, it sends data to the voice module 201 via pin 2 of the main control chip 200. The voice module 201 outputs the corresponding waveform, which is then used by the speaker 110 to complete the corresponding voice broadcast.

[0040] like Figure 7 The heater body 100 also includes a tilt switch module 206, which comprises a tilt switch QD, resistors R23 and R25. One end of resistor R25 is connected to pin 1 of QD, and the other end is connected to 5V. One end of resistor R23 is connected to pin 4 of QD, and the other end is connected to 5V. Pin 4 of QD is connected to pin 4 of IC1. When the heater tilts to a position different from the initially set angle, the infrared light path of the tilt switch is interrupted, outputting a low-level signal "Switch". This signal is received by pin 4 of the main control chip 200, which determines that the heater is in a tilted state and performs the corresponding operation.

[0041] like Figure 9 Button 109 includes six buttons: power, timer, oscillation, mode, plus, and minus. Figure 8 Resistors R1, R2, and R3 of the button circuit 207 are connected to the 2nd port of the switch, timer, rocker, and pin header KEY, respectively. Resistors R4, R5, and R6 of the button circuit are connected to the 1st port of the mode, plus, minus, and pin header KEY, respectively. The 3rd port of the pin header KEY is connected to the other end of the switch, timer, rocker, mode, plus, minus buttons. Resistors R19 and R22 of the power board are connected to 5V. Resistor R10 is connected to pin 15 of the main control chip 200, and resistor R16 is connected to pin 12 of the main control chip 200. The main control chip 200 determines whether a button is pressed by detecting the voltage change of pins 15 and 12. When a button is pressed by a finger, it is equivalent to connecting a resistor in series to ground. The voltage changes accordingly based on the different resistors R1-R6. The main control chip 200 then determines which corresponding channel button 109 is pressed based on the different voltages and performs the relevant button 109 operation.

[0042] like Figure 6 The head-shaking module 208 includes a thyristor TR1 and a resistor R17. The resistor R17 is connected to pin 3 of the main control chip 200. The anode of TR1 is connected to ACL, the cathode is connected to the head-shaking output, and the gate is connected to R17. When the main control chip 200 receives the head-shaking signal from the button 109, its pin sends a high level to R17, which turns on the thyristor and drives the head-shaking operation.

[0043] like Figure 8 The digital tube module 209 receives the output signal from the main control chip 200 and displays numbers on the panel.

[0044] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
