[0001] This utility model relates to the field of pet house technology, and in particular to a safe temperature-controlled pet heating house that delivers warm air through pipes and has a specific circuit control structure. Background Technology

[0002] In winter or low-temperature environments, heated pet houses are a common device for keeping pets warm. Most heated pet houses on the market currently use a mattress with built-in heating wires. These heating wires are directly powered by 220V high voltage and are energized during operation. Because pets have a habit of chewing and scratching the mattress, if the mattress is damaged, the heating wires can easily become exposed and live, posing a risk of electric shock to the pet or user. Furthermore, damaged heating wires may overheat and ignite surrounding flammable materials, further creating a fire hazard and compromising safety. Summary of the Invention

The heating and air supply assembly internally includes a heating element J1, a fan, and a control module. The pet house body internally includes a temperature sensor NTC1. The control module is electrically connected to the heating element J1, the fan, and the temperature sensor NTC1, and is used to control the start and stop of the heating element J1 and the fan based on the temperature signal detected by the temperature sensor NTC1. The heating and air supply assembly and the pet house body are independently set up, and the two are connected by the air supply duct to form a heat transfer channel. The heating and air supply assembly internally integrates the heating element J1, the fan, and the control module, wherein the heating element J1 is a heat generating component, and the fan is used to blow the heat generated by the heating element to the pet house body through the air supply duct; the heating and air supply assembly also has an air inlet to provide an air intake channel for the fan. The temperature sensor NTC1 is installed inside the pet house body for real-time monitoring of its internal temperature.

[0005] The control module includes an MCU chip U3, operation buttons, and a digital display U6. The operation buttons are connected to the signal input terminal of the MCU chip U3, and the digital display U6 is connected to the display output terminal of the MCU chip U3. The MCU chip U3 is connected to a silicon controlled rectifier (SCR) Q4 via its OUT_HEAT control terminal. The SCR Q4 is connected in series with the heating element J1 and powered on. The MCU chip U3 controls the start and stop of the heating element J1 by controlling the on and off states of the SCR Q4. The MCU chip U3 is also directly electrically connected to the fan motor MOT via its OUT_FAN control terminal to control the start and stop of the fan. The control module is the core of the entire device's control system, specifically comprising the MCU chip U3, operation buttons, and a digital display. The operation buttons are connected to the signal input terminal of the MCU chip U3, and the digital display is connected to the display output terminal of the MCU chip U3.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-2 As shown, a preferred embodiment of a safe temperature-controlled pet heating house includes a heating and air supply assembly 1, a pet house body 2, and an air supply duct 3 connecting the two. The heating and air supply assembly 1 contains a heating element J1 (5), a fan 6, and a control module. The pet house body 2 contains a temperature sensor NTC1. The control module is electrically connected to the heating element J1 (5), the fan 6, and the temperature sensor NTC1, and is used to control the start and stop of the heating element J1 (5) and the fan 6 according to the temperature signal detected by the temperature sensor NTC1. The heating and air supply assembly 1 and the pet house body 2 are spaced apart. The two ends of the air supply duct 3 are connected to the air outlet of the heating and air supply assembly 1 and the air inlet of the pet house body 2, respectively. The heating element J1 (5), the fan 6, and the control module are installed inside the heating and air supply assembly 1; the NTC temperature sensor is fixedly installed inside the pet house body 2.

[0024] The control module includes an MCU chip U3, operation buttons, and a digital tube U6. The operation buttons are connected to the signal input terminal of the MCU chip U3, and the digital tube U6 is connected to the display output terminal of the MCU chip U3. The MCU chip U3 is connected to a thyristor Q4 through the OUT_HEAT control terminal. The thyristor Q4 is connected in series with the heating element J1(5) and connected to the power supply. The MCU chip U3 controls the start and stop of the heating element J1(5) by controlling the conduction and cutoff of the thyristor Q4. The MCU chip U3 is directly connected to the motor MOT of the fan 6 through the OUT_FAN control terminal to control the start and stop of the fan 6, thus forming a complete signal acquisition and control loop.

[0025] The temperature sensor NTC1 is an NTC temperature sensor. The MCU chip U3 is provided with an AD detection port. The temperature sensor NTC1 is electrically connected to the MCU chip U3 through the AD detection port and is used to transmit the real-time temperature signal inside the pet house body 2 to the MCU chip U3.

[0026] The operation buttons include an ON / OFF button SW1 for powering on / off, a MODE button SW2 for setting the temperature level, and a TIME button SW3 for setting the timer. The digital tube U6 is used to display the set temperature level and timer.

[0027] The heating element J1(5) is a high-temperature resistant insulating heating wire, the fan 6 is a low-noise axial flow fan, the MCU chip U3 is a conventional 8-bit microcontroller, model JZ8P2605, and the thyristor Q4 is a bidirectional thyristor adapted to the power of the heating element to ensure stable operation of the equipment with low noise and precise control.

[0028] The temperature setting can be adjusted from 20℃ to 50℃, and the timer can be adjusted from 1 hour to 24 hours.

[0029] The heating and air supply assembly 1 is provided with an air inlet 4, which corresponds to the air inlet end of the fan 6.

[0030] It also includes a power supply circuit module, which is used to convert external AC power into an appropriate voltage to power the heating element J1(5), fan 6 and control module. The power supply circuit module includes a power input interface, a rectifier and filter unit and a voltage regulator circuit unit connected in sequence. The power supply circuit module realizes the function of "AC input → power protection → AC-DC conversion → voltage regulation output", and provides appropriate voltage regulation power supply for the heating element J1(5), fan 6 and control module of the pet heating house. The power supply circuit module is the core of the equipment's power supply, responsible for power conversion, voltage regulation and safety protection. Its specific structure and function are as follows: 1. Core components: including a power input interface, a rectifier and filter unit and a voltage regulator circuit unit. Each component is connected in series or integrated in the power supply circuit to form a complete power processing link. 2. Power supply logic: High voltage power supply circuit: After the power input interface is connected to 220V AC mains power, it directly powers the heating element J1(5) and fan 6 connected in series with the thyristor Q4. The on and off of this circuit is indirectly controlled by the MCU chip U3 through the thyristor Q4 and the OUT_FAN control terminal. Low-voltage power supply circuit: The 220V AC mains power is converted into pulsating DC by the rectifier and filter unit, and then regulated to 5V or 3.3V low-voltage DC by the voltage regulator circuit, providing stable power supply for low-voltage components such as MCU chip U3, digital tube U6, operation buttons, temperature sensor NTC1 and thyristor Q4 control terminal.

[0031] The optimal implementation process of a safe, temperature-controlled pet heating house is as follows:

[0032] 1. The user turns on the device using the ON / OFF button SW1, and then sets the target temperature range (20℃-50℃) and timer duration (1 hour-24 hours) using the MODE button SW2 and TIME button SW3 respectively. The set parameters are displayed on the digital tube U6.

[0033] 2. The MCU chip U3 receives the real-time temperature signal transmitted by the temperature sensor NTC1 through the AD detection port. When the real-time temperature is lower than the set temperature, the MCU chip U3 controls the thyristor Q4 to conduct through the OUT_HEAT control terminal to start the heating element J1(5) to heat. At the same time, the fan 6 is turned on through the OUT_FAN control terminal, and the generated warm air is sent into the pet house body 2 through the air supply pipe 3.

[0034] 3. When the temperature sensor NTC1 detects that the real-time temperature inside the pet house body 2 is higher than the set temperature, the MCU chip U3 turns off the thyristor Q4 through the OUT_HEAT control terminal, turns off the heating element J1 (5), and turns off the fan 6 through the OUT_FAN control terminal to stop supplying heat.

[0035] 4. Repeat steps 2 and 3 to achieve stable temperature control inside the pet house body 2;

[0036] 5. When the device reaches the set timeout period, the MCU chip U3 controls the entire device to automatically shut down.

[0037] When in use, the user presses the ON / OFF button SW1 to turn on the device, sets the temperature to 30℃ using the MODE button SW2, and sets the timer to 8 hours using the TIME button SW3. The digital tube U6 displays "30℃" and "8H" simultaneously. The MCU chip U3 receives the real-time temperature signal detected by the temperature sensor NTC1 through the AD detection port. When the temperature is below 30℃, the MCU chip U3 outputs a control signal through the OUT_HEAT control terminal to turn on the thyristor Q4, and the heating element J1(5) starts heating. At the same time, the MCU chip U3 outputs a signal through the OUT_FAN control terminal to control the fan 6 to run, and the warm air is sent into the pet house body 2 through the air supply pipe 3. When the temperature is above 30℃, the MCU chip U3 turns off the thyristor Q4 through the OUT_HEAT control terminal, turns off the heating element J1(5), and turns off the fan 6 through the OUT_FAN control terminal. The device continues to adjust according to the above logic until it has run for 8 hours, at which point the MCU chip U3 controls the entire device to automatically shut down.

[0038] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
