Description

Technical Field

[0001] This invention belongs to the field of heaters, specifically, it relates to a graphene smart heater with constant temperature function. Background Technology

[0002] With the improvement of residents' living standards and the promotion of clean heating policies in winter, consumers' demand for heating equipment has upgraded from simply "keeping warm" to "comfort, health, energy saving, environmental protection, intelligence, and convenience." Traditional heating equipment mainly includes resistance wire heaters, oil-filled radiators, and air conditioning heat pump systems, which, while meeting basic heating needs to a certain extent, still provide adequate heating.

[0003] However, these traditional heating devices still have many shortcomings in actual use. For example, resistance wire heaters often have excessively high local temperatures, which can easily cause burns, and the heat distribution is uneven, limiting the heating range. Oil-filled radiators heat up slowly, and the heat-conducting oil inside may age after long-term use, affecting heating efficiency and safety. Air conditioning heat pump systems experience a significant decrease in heating efficiency in low-temperature environments, and may even shut down, failing to reliably meet the heating needs of cold regions. In addition, some traditional heating devices have high energy consumption, which does not conform to the current trend of energy conservation and environmental protection. They also lack intelligent temperature control functions, making it difficult to achieve precise constant temperature, resulting in large fluctuations in indoor temperature and affecting the user's comfort experience.

[0004] In view of this, the present invention is proposed. Summary of the Invention

The intelligent constant temperature system is electrically connected to the first temperature sensor, the second temperature sensor, the multi-layer composite graphene heating plate, and the crossflow fan. A brush corresponding to the filter plate is slidably fitted inside the air inlet box. An impeller is rotatably fitted inside the air inlet box near the air inlet protective plate. A reciprocating assembly connected to the brush is installed inside the upper side of the air inlet box. The reciprocating assembly is driven by the impeller.

[0007] Optionally, the multilayer composite graphene heating plate includes a substrate, a conductive layer disposed on one side of the substrate, and an insulating layer disposed on one side of the conductive layer.

[0008] Optionally, the intelligent constant temperature system includes a microprocessor module, a temperature acquisition module, a heating control module, a fan control module, and a user interaction module.

[0009] Optionally, the temperature acquisition module is connected to the first temperature sensor and the second temperature sensor respectively, for real-time acquisition of the ambient temperature at the air inlet and the heated air temperature at the air outlet, and transmits the acquired temperature signal to the microprocessor module; the microprocessor module calculates the required heating power and fan speed based on the target temperature set by the user through the control panel, and the received air inlet and air outlet temperatures, through a built-in PID control algorithm or other intelligent control logic.

[0010] Optionally, the heating control module adjusts the working power of the multi-layer composite graphene heating plate according to the instructions of the microprocessor module to achieve precise control of the heating temperature; the fan control module adjusts the operating speed of the crossflow fan according to the instructions of the microprocessor module to match the current heating power and ensure uniform output and efficient convection of hot air; the user interaction module works with the control panel to receive user operation commands for temperature setting and mode selection, and can display the current set temperature, actual operating temperature, and equipment working status in real time.

[0011] Optionally, the upper side of the air inlet box is provided with a groove, and the reciprocating assembly includes a turntable rotatably engaged in the groove, a slide plate slidably engaged in the groove, a groove opened on one side of the slide plate, and a slider installed on one side of the turntable. The slider is located in the groove, the brush is installed at one end of the slide plate, and the turntable is driven to engage with the impeller.

[0012] Optionally, grooves are provided on both sides of the groove, and movable blocks that are fixedly connected to both sides of the slide plate are slidably fitted in the grooves.

[0013] Optionally, the upper side of the air inlet box is provided with an inner cavity that communicates with the groove. A rotating rod that is fixedly connected to the impeller is rotatably fitted inside the inner cavity.

[0014] Optionally, a mounting plate is provided on one side of the filter plate, and a plurality of fastening screws are provided on one side of the mounting plate that are threaded into the air inlet box.

[0015] Optionally, a fixing groove communicating with the placement groove is provided on one side of the air inlet box, and a collection box is provided in the fixing groove, with the bottom of the filter plate located in the collection box.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: The intelligent constant temperature system set in the control panel combines the real-time ambient temperature of the air inlet collected by the first temperature sensor and the heated air temperature of the air outlet collected by the second temperature sensor. The microprocessor module calculates the target temperature set by the user using intelligent logic such as PID control algorithm. Subsequently, the heating control module adjusts the working power of the multi-layer composite graphene heating plate accordingly to ensure stable and controllable heating temperature. The fan control module simultaneously adjusts the speed of the crossflow fan to match the output of hot air with the heating power, thereby achieving rapid attainment and stable maintenance of the indoor temperature at the set value. This effectively avoids the problem of large temperature fluctuations in traditional heating equipment and significantly improves the user's comfort experience. At the same time, the multi-layer composite graphene heating plate adopts a composite structure of substrate, conductive layer and insulating layer, which not only has high heating efficiency and rapid heating, but also uniform heating, avoiding local high temperature phenomenon and making it safer to use. The filter plate effectively filters the air entering the heater housing, removing dust, hair, and other impurities. This prevents impurities from adhering to the surface of the multi-layer composite graphene heating plate and affecting heating efficiency. It also reduces the secondary stirring of indoor dust, improving indoor air quality. The brush, when the crossflow fan is activated, directs airflow through the air intake box, passing over the air intake guard plate and rotating the impeller. The impeller's rotation drives a reciprocating component, causing a sliding block to slide back and forth. This sliding block, in turn, causes the brush at one end to clean the filter plate surface, effectively removing dust and impurities. This prevents the filter plate from becoming clogged, ensuring the heater can continuously and stably draw in cold air for heating. The dust swept off by the brush falls naturally into a collection box at the bottom of the filter plate, allowing users to easily remove and clean it periodically. This significantly reduces the frequency and difficulty of manual filter cleaning, making maintenance more convenient.

[0021] The invention will now be described in further detail with reference to the accompanying drawings.

[0022] Please see Figures 1-6 As shown, this embodiment provides a graphene smart heater with constant temperature function, including: an air inlet box 1 and a heater shell 2. The air inlet box 1 is located on one side below the heater shell 2. An air inlet protective plate 17 is provided on one side of the air inlet box 1. An air outlet protective plate 18 is provided on the upper side of the heater shell 2. A filter plate 7 is provided inside the air inlet box 1. A multi-layer composite graphene heating plate 3 is provided inside the heater shell 2. A crossflow fan 11 located on one side of the multi-layer composite graphene heating plate 3 is provided inside the heater shell 2. A first temperature sensor 20 is installed on the air inlet protective plate 17, a second temperature sensor 21 is installed on the air outlet protective plate 18, and a control panel 19 is installed on one side of the heater housing 2. An intelligent constant temperature system is installed in the control panel 19. The intelligent constant temperature system is electrically connected to the first temperature sensor 20, the second temperature sensor 21, the multi-layer composite graphene heating plate 3, and the crossflow fan 11. A brush 8 corresponding to the filter plate 7 is slidably fitted inside the air inlet box 1. An impeller 9 is rotatably fitted inside the air inlet box 1 near the air inlet protective plate 17. A reciprocating assembly 10 connected to the brush 8 is installed on the upper side of the air inlet box 1. The reciprocating assembly 10 is driven by the impeller 9.

[0023] The intelligent constant temperature system set in the control panel 19 combines the real-time ambient temperature of the air inlet collected by the first temperature sensor 20 and the heated air temperature of the air outlet collected by the second temperature sensor 21. The microprocessor module accurately calculates the target temperature set by the user using intelligent logic such as PID control algorithms. Subsequently, the heating control module adjusts the working power of the multi-layer composite graphene heating plate 3 accordingly to ensure stable and controllable heating temperature. The fan control module simultaneously adjusts the speed of the crossflow fan 11 to match the hot air output with the heating power, thereby achieving rapid attainment and stable maintenance of the indoor temperature at the set value. This effectively avoids the problem of large temperature fluctuations in traditional heating equipment, significantly improving user comfort. Furthermore, the multi-layer composite graphene heating plate 3 adopts a composite structure of substrate 301, conductive layer 302, and insulating layer 303, which not only has high heating efficiency and rapid temperature rise but also provides uniform heating, avoiding localized high temperatures and making it safer to use. The filter plate 7 further filters the incoming air. The air entering the heater housing 2 is effectively filtered to remove dust, hair, and other impurities, preventing them from adhering to the surface of the multi-layer composite graphene heating plate 3 and affecting heating efficiency. This also reduces secondary dust re-entrainment, improving indoor air quality. Through the brush 8, when the crossflow fan 11 is activated, the air in the air inlet box 1 flows through the air inlet protective plate 17 and drives the impeller 9 to rotate. The rotation of the impeller 9 drives the moving block to slide back and forth through the reciprocating assembly 10. The reciprocating motion of the slide plate 1002 then drives the brush 8 at one end to perform a back-and-forth sweeping motion on the surface of the filter plate 7, effectively removing dust and impurities adhering to the filter plate 7 and preventing blockage that could affect air intake efficiency. This ensures the heater can continuously and stably draw in cold air for heating. The dust swept off by the brush 8 falls naturally into the collection box 6 located at the bottom of the filter plate 7, allowing users to easily remove and clean the collection box 6 periodically. This effectively reduces the frequency and difficulty of manually cleaning the filter plate 7, making maintenance more convenient.

[0024] like Figure 3As shown, the multilayer composite graphene heating plate 3 of this embodiment includes a substrate 301, a conductive layer 302 disposed on one side of the substrate 301, and an insulating layer 303 disposed on one side of the conductive layer 302.

[0025] The substrate 301 is made of high-temperature resistant ceramic fiber board with good thermal conductivity, and its thickness is controlled at 3-5mm. This provides stable structural support for the entire heating plate and ensures uniform heat conduction. The conductive layer 302 is made of graphene and nano-silver paste composite and is uniformly coated on the surface of the substrate 301 through screen printing. The coating thickness is about 8-12μm. This composite conductive layer not only has extremely low sheet resistance [≤10Ω / □], ensuring good conductivity and heating efficiency, but also the unique two-dimensional structure of graphene allows heat to be dissipated quickly in a planar form, greatly improving the uniformity of heat dissipation. Uniformity; the insulating layer 303 is made of high-purity mica sheet or polyimide film with a thickness of 0.1-0.2mm, which is tightly attached to the outside of the conductive layer 302. Its breakdown voltage is ≥20kV / mm, which can effectively isolate current and prevent leakage accidents. At the same time, the mica sheet and polyimide film themselves also have excellent high temperature resistance (long-term operating temperature can reach above 200℃) and thermal conductivity, which will not hinder the transfer of heat. In addition, a high-temperature resistant silicone sealing ring is also provided on the edge of the multilayer composite graphene heating plate 3, which further improves its overall insulation and sealing performance and ensures safe use.

[0026] The intelligent constant temperature system of this embodiment includes a microprocessor module, a temperature acquisition module, a heating control module, a fan control module, and a user interaction module. The temperature acquisition module is connected to the first temperature sensor 20 and the second temperature sensor 21, respectively, to collect the ambient temperature at the air inlet and the heated air temperature at the air outlet in real time, and transmit the collected temperature signals to the microprocessor module. The microprocessor module calculates the required heating power and fan speed based on the target temperature set by the user through the control panel 19, as well as the received air inlet and air outlet temperatures, using a built-in PID control algorithm or other intelligent control logic. The heating control module adjusts the working power of the multilayer composite graphene heating plate 3 according to the instructions of the microprocessor module to achieve precise control of the heating temperature. The fan control module adjusts the operating speed of the crossflow fan 11 according to the instructions of the microprocessor module to match the current heating power and ensure uniform output and efficient convection of hot air. The user interaction module works with the control panel 19 to receive the user's temperature setting and mode selection operation instructions, and can display the current set temperature, actual operating temperature, and equipment working status in real time.

[0027] The microprocessor module, as the core of the intelligent constant temperature system, uses a high-performance industrial-grade chip, possessing rapid data processing capabilities and stable operating performance. It can simultaneously process multiple temperature signals and control commands, ensuring rapid system response and precise control. The temperature acquisition module uses a high-precision digital temperature sensor with a measurement range covering -20℃ to 100℃ and an accuracy of ±0.5℃. It accurately captures subtle temperature changes at the air inlet and outlet, providing a reliable basis for the microprocessor module's control decisions. The heating control module incorporates a thyristor power regulation circuit, enabling smooth adjustment of heating power from 0 to rated power, avoiding temperature fluctuations caused by sudden power changes in traditional heating methods. This achieves a temperature control accuracy of ±1℃ for the multi-layer composite graphene heating plate. The fan control module employs PWM (Pulse Width Modulation) technology. The crossflow fan features stepless speed regulation, offering a wide range of adjustable speeds, from quiet operation at low settings to rapid heating at high settings, meeting the heating needs of various scenarios. Precise fan speed control ensures optimal convection circulation of hot air indoors, improving heating uniformity and comfort. The user interface module is equipped with a high-definition LED digital display screen, clearly showing the set temperature, real-time ambient temperature, outlet temperature, current operating mode (e.g., heating, energy saving, timer), and device status indicators (e.g., running, standby, fault). The control panel features touch-sensitive buttons, allowing users to easily set temperatures, switch modes, and set timers. Some models also support remote APP control, enabling users to adjust heater parameters anytime, anywhere via their mobile phones for a smart home heating experience.

[0028] like Figures 4-6 As shown, the air inlet box 1 of this embodiment has a groove 12 on its upper side. The reciprocating assembly 10 includes a turntable 1001 rotatably fitted in the groove 12, a slide plate 1002 slidably fitted in the groove 12, a groove 1003 on one side of the slide plate 1002, and a slider 1004 mounted on one side of the turntable 1001. The slider 1004 is located in the groove 1003. A brush 8 is mounted on one end of the slide plate 1002. The turntable 1001 is driven by the impeller 9. Both sides of the groove 12 have channels, and movable blocks that are fixedly connected to both sides of the slide plate 1002 are slidably fitted in the channels. The upper side of the air inlet box 1 has an inner cavity 13 that communicates with the groove 12. A rotating rod 14 that is fixedly connected to the impeller 9 is rotatably fitted in the inner cavity 13. Synchronous pulleys 15 are mounted on the periphery of the rotating rod 14 and on one side of the turntable 1001. A synchronous belt 16 is sleeved between the two synchronous pulleys 15.

[0029] When the crossflow fan 11 is started, external air enters the air inlet box 1 through the air inlet protective plate 17. During the airflow, the airflow impacts the impeller 9, causing the impeller 9 to rotate around its axis. The rotation of the impeller 9 is transmitted to the synchronous pulley 15 in the inner cavity 13 through the rotating rod 14 fixedly connected to it. The synchronous pulley 15 drives another synchronous pulley 15 in the groove 12 and the turntable 1001 fixedly connected to it to rotate synchronously through the synchronous belt 16. When the turntable 1001 rotates, the slider 1004 installed on one side slides in the groove 1003 opened on the side of the slide plate 1002. Since the groove 1003 is a long groove with a specific trajectory, the circular motion of the slider 1004 is converted into the slide plate 1002 sliding along the groove 12. The reciprocating linear motion of the channels on both sides allows the movable blocks fixedly connected to both sides of the slide plate 1002 to slide within the channels, providing guidance and stable support for the reciprocating motion of the slide plate 1002. The brush 8 installed at one end of the slide plate 1002 then sweeps back and forth across the surface of the filter plate 7, thereby sweeping off the dust, hair, and other impurities trapped on the filter plate 7. The swept-off impurities fall naturally under the action of gravity and enter the collection box 6 pre-set at the bottom of the filter plate 7. Users only need to periodically pull the collection box 6 out of the air inlet box 1 to easily empty and clean the dust and impurities inside without disassembling the filter plate 7, which greatly simplifies the maintenance process and ensures the long-term effective filtration and air intake efficiency of the filter plate 7.

[0030] like Figure 1 As shown, in this embodiment, a mounting plate 4 is installed on one side of the filter plate 7, and a plurality of fastening screws 5 are provided on one side of the mounting plate 4 that are threadedly engaged with the air inlet box 1.

[0031] By tightening screws 5, the mounting plate 4 can be firmly fixed in the preset installation position of the air inlet box 1, thereby achieving stable assembly of the filter plate 7 inside the air inlet box 1. When the filter plate 7 needs to be deeply cleaned, replaced or repaired, the user only needs to use a screwdriver or other tools to loosen and remove the tightening screws 5, and the mounting plate 4 together with the filter plate 7 can be pulled out of the air inlet box 1. The operation is convenient and provides convenient conditions for the maintenance of the filter plate 7, ensuring the continuous and stable operation of the filtration system.

[0032] like Figure 4 As shown, in this embodiment, the air inlet box 1 has a fixing groove on one side that communicates with the placement groove. The fixing groove contains a collection box 6, and the bottom of the filter plate 7 is located inside the collection box 6.

[0033] The collection box 6 provides a dedicated space for the impurities swept down by the filter plate 7. Its top opening faces the bottom of the filter plate 7, ensuring that dust, hair, and other impurities that fall during cleaning can fall accurately into it, preventing impurities from scattering into other areas inside the air inlet box 1 and causing secondary pollution or cleaning difficulties. The collection box 6 is connected to the fixing slot by a sliding fit, which allows users to easily pull it out or push it in. This pull-out design makes the cleaning of impurities simpler and faster, without the need for additional tools, further improving the convenience of equipment maintenance.

[0034] Working Principle: When the user sets the target temperature via control panel 19, the intelligent constant temperature system immediately starts working. The first temperature sensor 20 monitors the ambient temperature at the air inlet in real time, while the second temperature sensor 21 continuously collects the air temperature after it has been heated by the multi-layer composite graphene heating plate 3 at the air outlet. These temperature signals are transmitted to the microprocessor module. The microprocessor module compares and analyzes the collected actual temperature with the target temperature set by the user, and uses built-in intelligent logic such as PID control algorithm to accurately calculate the heating power required to reach and maintain the target temperature and the matching fan speed. Subsequently, the microprocessor module sends instructions to the heating control module and the fan control module. According to the instructions, the heating control module adjusts the working power of the multi-layer composite graphene heating plate 3 through the thyristor power adjustment circuit. The conductive layer 302 on the substrate 301 heats up rapidly under the action of current. The heat is efficiently conducted through the substrate 301 and the insulating layer 303 and radiated outward. At the same time, according to the instructions, the fan control module adjusts the speed of the crossflow fan 11 using PWM technology. The machine 11 draws in external cold air from the air inlet box 1. The air first passes through the air inlet protective plate 17 to initially block larger impurities, and then flows through the filter plate 7. The filter plate 7 effectively removes fine impurities such as dust and hair from the air. During this process, the airflow generated by the start of the crossflow fan 11 drives the impeller 9 to rotate. The impeller 9 drives the turntable 1001 to rotate through the rotating rod 14, the synchronous pulley 15, and the synchronous belt 16. The slider 1004 on the turntable 1001 slides in the groove 1003 of the slide plate 1002, converting the circular motion into the slide plate 1002. The reciprocating linear motion of the 2 causes the brush 8 to sweep back and forth on the surface of the filter plate 7, preventing the filter plate 7 from clogging. The swept-down impurities fall into the collection box 6 at the bottom. The filtered clean air is drawn into the heater housing 2 and heated by the multi-layer composite graphene heating plate 3, becoming hot air that is blown out from the air outlet. By intelligently adjusting the heating power and fan speed, the output of hot air is precisely matched with the heating power, so that the indoor temperature can quickly reach the user's set value and be maintained stably, achieving efficient, comfortable and intelligent constant temperature heating.
