Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0016] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0017] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0018] Reference Figure 1-5A small-sized fan heater that precisely covers localized areas includes a housing consisting of a bottom shell 1 and a front shell 2. A fan 4 driven by a motor 3 is installed inside the housing. An air inlet grille 5 is located on the rear side of the bottom shell 1, and a rotatable, adjustable air outlet cover 6 is installed on the front side of the housing. An air outlet grille 7 is provided on the air outlet cover 6. A PCT heating element controlled by a temperature control sensor is installed inside the air outlet cover 6. The PCT heating element is hidden behind the grille ribs of the air outlet grille 7 to avoid affecting the smoothness of airflow. The heater is small in size and compact in structure. The adjustable air outlet cover allows for precise control of the heating range, making it suitable for localized heating scenarios such as bedside areas in bedrooms and office desks. The temperature control sensor ensures safety and heating stability. It combines portability, energy efficiency, and scenario adaptability, solving the problem that existing heating devices cannot accurately meet the personalized heating needs of localized areas.

[0019] The lower inner wall of the air outlet cover 6 is provided with mounting holes 8. The temperature control sensor is fixed in the mounting holes 8 by screws. The top surface of the temperature control sensor is in contact with the PCT heating element, or there is a gap of 0.5 mm to 2 mm between the top surface of the temperature control sensor and the PCT heating element. This allows for real-time and accurate monitoring of the heating temperature, timely adjustment of the PCT heating element's working status, prevention of safety hazards caused by excessive temperature, and stable heating temperature, thus improving the user experience. Compared with small heaters without precise temperature control, the safety and reliability are significantly improved.

[0020] The housing is provided with a through hole, and the inner wall of the through hole is evenly provided with a plurality of first wave patterns (such as...). Figure 4 As shown in Figure A), the air outlet cover 6 has mounting shafts 9 at both ends that pass through the through holes, and the mounting shafts 9 have a second wave pattern corresponding to the first wave pattern (as shown in Figure A). Figure 5 As shown in B), it can achieve stable adjustment and positioning of the air outlet angle, and is not easy to loosen.

[0021] Furthermore, both the through hole and the mounting cavity of the impeller 4 consist of two parts: one part is located on the bottom shell 1 and the other part is located on the front shell 2. During installation, the impeller 4 and the air outlet cover 6 are placed on the bottom shell 1, and the front shell 2 is fixed on the bottom shell 1 to complete the installation of the impeller 4 and the air outlet cover 6.

[0022] Furthermore, the two ends of the wind turbine 4 can be fixed inside the housing by bearings to improve the smoothness of rotation.

[0023] The bottom shell 1 is provided with an isolation part 10 between the wind turbine 4 and the air inlet grid 5. The surface of the isolation part 10 is provided with a number of fasteners 11 for fixing the wires, which can fix the wires in a regular manner, prevent the wind turbine from getting tangled with the wires when it rotates, improve the stability of the equipment operation, and simplify the internal structure layout, making it easier to produce, assemble and maintain later.

[0024] The air inlet grille 5 is located on the side of the isolation section 10 away from the impeller 4. The side of the isolation section 10 away from the impeller 4 is inclined from bottom to top towards the impeller 4, which can guide the airflow to enter the housing smoothly. After being driven by the impeller, the airflow passes through the PCT heating element and is discharged from the air outlet grille, reducing airflow resistance, improving air outlet efficiency, and avoiding mutual interference between air inlet and outlet, ensuring rapid heating of local areas and optimizing the heating experience.

[0025] Furthermore, when this heater is wall-mounted, the outer wall of the bottom shell 1 will cover the air inlet grille 5, preventing dust and other environmental particles from falling directly onto the air inlet grille 5. Especially when the weather is warm, if the heater is not used and is hung on the wall, a lot of dust will accumulate on its surface. When the weather cools down, if the dust is not cleaned, a large amount of dust will be blown out, which is particularly unfriendly to users with allergies such as rhinitis. Therefore, the covering of the outer wall of the bottom shell 1 can effectively prevent this from happening.

[0026] The bottom surface of the base shell 1 is equipped with a hook fastener 12 and a support foot 13. It can achieve two modes of installation without additional accessories: wall mounting and flat placement on a desktop, stool, etc. When wall mounted, it does not occupy the limited space of the desktop or bedside. When placed flat, it has good stability. It can be flexibly switched according to the spatial characteristics of different scenarios such as bedrooms and offices, and is suitable for use in small spaces. It solves the defects of existing heaters in terms of single placement method and low space utilization.
