Description

Technical Field

[0001] This utility model relates to the field of heater structure technology, and in particular to a heater housing structure. Background Technology

[0002] Traditional heaters use a motor to blow air and a PTC heater to generate heat, raising the room temperature by blowing warm air. A round air outlet is a better choice for improving the airflow experience, but most heating elements are square, making it difficult to match the shape of the outlet. Using round heating elements would be too expensive to manufacture. Furthermore, to enhance the heater's aesthetics and functionality, lighting is often added to the cover. However, due to limited cover area, the lighting is usually placed inside the air outlet. But when the heating function is used, the hot air blowing from the outlet causes heat dissipation problems for the lighting, significantly reducing its lifespan. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a heater housing structure, including a housing and a cover plate for sealing the housing. The cover plate has an air outlet and an air inlet arranged side by side. The air outlet is a square hole, and the air inlet is a circular hole. A fan mounting slot is provided inside the housing corresponding to the air inlet, and a fan is installed in the fan mounting slot. An air duct is provided from the fan mounting slot to the other end of the housing. One end of the air duct communicates with the fan mounting slot, and the other end extends to below the air outlet. The air duct also communicates with a ventilation port on the side wall of the housing. A heating bracket is provided inside the air outlet, and a heating device is installed inside the heating bracket. The top of the heating bracket is embedded in the air outlet, and the bottom of the heating bracket is located in the air duct. A flap device is provided in the air duct from the ventilation port to the heating bracket, and the flap can cover the ventilation port or the area from the fan mounting slot to the heating device. The system includes an air duct; a switching lighting device is installed above the air outlet; the switching lighting device includes a base, a lamp holder, and a lampshade; the base is a circular groove with a square air vent at the bottom corresponding to the air outlet; the lamp holder is installed inside the base, with a gap between the lamp holder and the side wall of the base; the lamp holder includes a lower lamp holder and an upper lamp holder, both of which are groove-shaped structures with spherical bottom surfaces; the upper lamp holder is embedded in the lower lamp holder, and there is a gap between the bottom surfaces of the upper and lower lamp holders; a heat dissipation inlet is provided at one end of the bottom surface of the lower lamp holder, and a heat dissipation outlet is provided at the other end of the lower lamp holder opposite to the heat dissipation inlet; an air inlet is provided on the bottom surface of the base corresponding to the heat dissipation inlet, and an auxiliary heat dissipation vent is provided on the cover plate corresponding to the air inlet; a lamp plate is installed inside the upper base, and a lampshade is installed on the top of the upper base.

[0004] Furthermore, the width of the air duct is the same as the width of the air exchange outlet.

[0005] Furthermore, the oscillating structure includes a stepper motor and an oscillating blade. One end of the oscillating blade is provided with a rotating shaft, which is fixedly connected to the output end of the stepper motor. The stepper motor is located at the top of the side wall of the air duct.

[0006] Furthermore, the upper lamp holder sidewall is provided with a locking block, and the lower lamp holder sidewall is provided with a locking slot corresponding to the locking block. When the upper lamp holder and the lower lamp holder are connected, the locking block is embedded in the locking slot.

[0007] Furthermore, the base has an air inlet with a downward-facing air guide channel, the bottom of which is connected to the heat dissipation auxiliary channel.

[0008] Furthermore, the base sidewall is provided with a connecting post, and the cover plate is provided with a fixing hole corresponding to the connecting post. The connecting post and the fixing hole are screwed with screws to fix the base and the cover plate.

[0009] Furthermore, the base has a lamp holder connecting post on its bottom surface, and the lower lamp holder has a lamp holder fixing hole corresponding to the lamp holder connecting post. Screws are screwed into the lamp holder connecting post and the lamp holder fixing hole to fix the base and the lamp holder in place.

[0010] The beneficial effects of this utility model are as follows: 1. By converting the square air outlet on the cover plate into a round air outlet through the lighting conversion device, the airflow becomes more comfortable.

[0011] 2. There is a gap between the lower lamp holder and the upper lamp holder, which can form a heat dissipation air duct. Before entering the heating device, part of the air in the air duct enters the heat dissipation air duct from the heat dissipation auxiliary port, the base air inlet, and the heat dissipation inlet. After absorbing the heat generated by the lamp panel in the upper lamp holder, it enters the base from the heat dissipation outlet, forming warm air that is blown out from the gap between the base and the lamp holder. This can help dissipate heat from the lamp panel without affecting the hot air outlet.

[0012] 3. It is equipped with a flap structure, which can block the air duct or air exchange vent to switch between air exchange mode and air supply mode. Attached Figure Description
