[0034] See also Figure 1-5 As shown, according to an embodiment of the present application, a fan heater is provided, comprising:

[0035] The housing 1 comprises an upper housing 11 and a lower housing 12, with a mounting cavity defined between the upper housing 11 and the lower housing 12;

[0036] An air duct baffle 2 is provided in the housing 1. The air duct baffle 2 divides the installation cavity into a first chamber and a second chamber. The air duct baffle 2 includes a bottom plate 21 and a baffle 22. The bottom plate 21 is provided in the installation cavity. The baffle 22 is vertically provided on the bottom plate 21. An air duct opening is provided on the baffle 22.

[0037] a heater 3, the heater 3 being disposed in the first chamber;

[0038] An air source unit 4 is provided in the second chamber, and an output end of the air source unit 4 supplies gas into the first chamber through the air duct opening;

[0039] At least a portion of the bottom plate 21 is located between the air source portion 4 and the lower shell 12 .

[0040] The fan-type heater 3 provided in this embodiment includes an outer shell 1, an air duct baffle 2, a heater 3 and an air source part 4. The upper shell 11 and the lower shell 12 of the outer shell 1 together form a stable installation cavity, which provides good protection and installation space for the various components of the heater 3. The bottom plate 21 of the air duct baffle 2 can provide stable support for the baffle 22, ensuring that the baffle 22 is vertically located in the installation cavity, and can divide the installation cavity into two parts, a first cavity and a second cavity. The heater 3 is installed in the first cavity, and the air source part 4 is installed in the second cavity. The air duct baffle 2 can isolate the heater 3 from the air source part 4, reduce the impact of the heat source on other components, and improve the safety of use. The air duct opening opened on the baffle 22 can ensure that the gas output by the air source part 4 enters the first cavity and quickly transfers the heat generated by the heater 3 to the surrounding environment, thereby achieving a rapid heating effect.

[0041] When installing the air duct baffle 2, the air source unit 4 can press a portion of the bottom plate 21 against the lower shell 12. Therefore, the air duct baffle 2 can be fixed to the lower shell 12 without welding. This eliminates the need to weld the air duct baffle 2 to the lower shell 12 before manufacturing the outer shell 1, improving the convenience of manufacturing the outer shell 1 in the early stages. Furthermore, this also facilitates the installation of the heater 3. At this time, the air duct baffle 2 is not installed when the heater 3 is installed, preventing interference between the heater 3 installation and the air duct baffle 2, thereby improving installation efficiency. When the air duct baffle 2 is installed in the installation cavity, both sides of the baffle 2 can contact the side walls of the lower shell 12, further improving stability after installation.

[0042] Fan heater, also including:

[0043] The first fixing column 5 is disposed in the first chamber, and the heater 3 is connected to the first fixing column 5 .

[0044] In this technical solution, the first insulating plate 31 serves as the bottom layer of the heater 3. It effectively prevents leakage of current generated by the heater 32, thereby preventing potential safety hazards to surrounding components and users. The first insulating plate 31 is typically made of a material with excellent insulating properties, such as ceramic or mica. Its thickness and material are carefully selected to ensure reliable insulation protection under various operating conditions.

[0045] The heater 32 is located above the first insulating plate 31. Heating element 32 can utilize a variety of heating technologies, such as resistance heating and electromagnetic heating, depending on the application. During operation, the heater 32 converts electrical energy into thermal energy, which is then transferred to the surrounding air through heat conduction and radiation.

[0046] The second insulating plate 33 is positioned above the heater 32, further enhancing the insulation performance of the heater 3. Similar to the first insulating plate 31, the second insulating plate 33 is also made of an insulating material. It prevents electrical contact between the pressing plate 34 and other components above the heater 32 and the heater 32, ensuring the safe operation of the heater 3. The second insulating plate 33 also provides thermal insulation, reducing the amount of heat transferred from the heater 32 to the pressing plate 34, lowering the temperature of the pressing plate 34 and improving the overall stability of the heater 3.

[0047] The pressure plate 34 is located at the top of the heater 3. Its primary function is to secure the first insulating plate 31, the heating element 32, and the second insulating plate 33 to the first fixing post 5. Typically made of metal, the pressure plate 34 possesses sufficient strength and rigidity to withstand a certain amount of pressure. By connecting to the first fixing post 5, the pressure plate 34 ensures that the various components of the heater 3 are tightly coupled, preventing them from loosening or shifting during operation.

[0048] The arrangement of the first insulating plate 31, the heating element 32, the second insulating plate 33, and the pressure plate 34 connected to the first fixing post 5 enables the heater 3 to operate stably. The first fixing post 5 provides reliable support and fixing points for these components, ensuring that they will not be displaced due to vibration or external forces during the operation of the heater 3. At the same time, this connection method also facilitates the installation and removal of the heater 3. Split heaters 3 can be installed on the first fixing post 5 in sequence, and integrated heaters 3 can also be installed on the first fixing post 5, providing more diverse installation options and more convenient operation.

[0049] A limiting protrusion 35 is provided on the first insulating plate 31 , and the limiting protrusion 35 is used to fix the heating body 32 .

[0050] In this technical solution, there are multiple limiting protrusions 35. The height and shape of each limiting protrusion 35 are set according to the size and shape of the heating body 32. They can closely fit the edge of the heating body 32 and effectively fix it. These limiting protrusions 35 are generally made of insulating material and are integrally formed with the first insulating plate 31 or fixed thereto by a reliable connection method.

[0051] It is understandable that during the installation of the heater 3, the limiting protrusion 35 can quickly and accurately position the heating body 32 to ensure that it is installed in the correct position. This not only improves the installation efficiency, but also reduces the risk of damage to the heating body 32 or performance degradation due to improper installation. Secondly, during the operation of the heater 3, the limiting protrusion 35 can prevent the heating body 32 from being displaced or shaking. Since a certain amount of vibration may be generated during operation, the presence of the limiting protrusion 35 can ensure that the heating body 32 always remains stable, thereby ensuring the uniformity and stability of the heating effect. In addition, the limiting protrusion 35 can also play a certain protective role, preventing the heating body 32 from colliding or rubbing with other components, thereby extending the service life of the heating body 32.

[0052] The fan heater also includes:

[0053] The power board 6 is disposed in the second chamber, and the power board 6 is located on one side of the gas source 4 . The power board 6 is electrically connected to the gas source 4 and the heater 3 .

[0054] In this technical solution, the power board 6 is located on one side of the gas source unit 4 in the second chamber, which not only avoids the risk of overheating caused by direct contact between the power board 6 and the heater 3, but also facilitates connection and cooperation with the gas source unit 4. The power board 6 is usually composed of high-quality electronic components and circuit boards, and can stably provide the required power to the gas source unit 4 and the heater 3. The power board 6 is electrically connected to the gas source unit 4 and the heater 3 through wires, achieving precise power supply control for these two key components. Through reasonable circuit design and electronic component configuration, the power board 6 can adjust the output voltage and current according to different working conditions and requirements, ensuring that the gas source unit 4 and the heater 3 operate at optimal performance.

[0055] The fan heater further includes a control mainboard 7 , which is disposed on the side wall of the lower shell 12 . The control mainboard 7 is located in the second cavity, and is electrically connected to the power board 6 .

[0056] In this technical solution, the control main board 7 is located in the second chamber on the side wall of the lower shell 12, which is convenient for electrical connection with the power board 6, and can effectively utilize space and avoid interference with other components. The control main board 7 is usually composed of a high-performance microprocessor, sensors and electronic components, which can achieve precise control of the fan heater 3. The control main board 7 is electrically connected to the power board 6, receives power supply from the power board 6, and controls the heater 3 and the air source part 4 through a series of circuits and signal transmissions. It can send instructions to the power board 6 according to the temperature, wind speed and other parameters set by the user, adjust the power of the heater 3 and the speed of the air source part 4, so as to achieve the desired heating effect and airflow output. At the same time, the control main board 7 can also monitor the operating status of the equipment in real time, such as temperature, current, voltage, etc. Once an abnormal situation is found, protective measures can be taken in time to ensure the safe operation of the equipment.

[0057] The fan heater further includes a power socket 8 , which is disposed on the side wall of the lower housing 12 and located on one side of the control main board 7 . The power socket 8 is electrically connected to the control main board 7 and the power board 6 .

[0058] In this technical solution, power socket 8 is located on the side wall of lower housing 12, on the side of control board 7. This arrangement not only facilitates user insertion and removal of the power plug, but also forms a reasonable electrical connection path between control board 7 and power board 6. Power socket 8 generally adopts a standardized design and is compatible with various common power plugs, providing users with a wide range of power supply options.

[0059] The power socket 8 is electrically connected to the control board 7 and the power board 6, allowing external power to be smoothly input into the fan heater 3. When the power plug is inserted into the power socket 8, the current first passes through the power socket 8 and then is transmitted to the control board 7 and the power board 6. The control board 7 can rationally distribute and control the power supply based on the operating status of the device and user-defined parameters, ensuring a stable power supply to the heater 3 and the air source 4. Furthermore, the power socket 8 is located away from the heater 3, further enhancing user safety.

[0060] The second fixing column 9 is disposed in the second chamber, and is used to fix the gas source 4 on the lower housing 12 .

[0061] In this technical solution, the second fixing column 9 is located in the second chamber, providing a reliable fixing point for the air source part 4. The second fixing column 9 and the lower shell 12 can be connected by bolts, welding or other reliable connection methods to ensure that the air source part 4 is firmly fixed on the lower shell 12 without loosening or displacement. At the same time, the second fixing column 9 is in contact with one side of the base plate 21 to limit the base plate 21 in the horizontal direction, further improving the stability of the base plate 21 after installation. The presence of the second fixing column 9 enables the air source part 4 to maintain a stable position during operation, thereby ensuring that the output airflow is stable and uniform. Stable airflow plays a key role in the efficient heating of the heater 3, and can quickly and evenly distribute heat to the surrounding environment, thereby improving the heating effect.

[0062] An air outlet is formed on a side of the lower housing 12 away from the control main board 7 .

[0063] The air source 4 is a fan.

[0064] In this technical solution, the turbofan serves as the air source 4 and can provide a strong and stable airflow, thereby ensuring that the heater 3 can quickly transfer heat to the surrounding environment and achieve a rapid heating effect.

[0065] The turbofan's small size and light weight make it easier to install in the fan heater 3. It fits compactly within the second chamber, minimizing space and adding weight to the overall device. This makes the fan heater 3 more portable and adaptable to a variety of scenarios.

[0066] The operation noise of the turbo fan is relatively low. This reduces the generation of excessive noise interference when the fan heater 3 is in operation, providing a quiet and comfortable use environment for the user.

[0067] Furthermore, turbofans offer high reliability and durability. They are typically made of high-quality materials with excellent wear and corrosion resistance, ensuring stable performance over extended periods of use. Their relatively simple structure also makes maintenance and upkeep easier, reducing equipment maintenance costs.
