Referring to fig. 1, a blowing structure includes: fan 230, air collection hood 300, separation assembly 900, and burner 700; the wind collecting cover 300 is connected with the fan 230 in a sealing way; the separation assembly 900 is arranged in the air collecting cover 300 and separates the internal space of the air collecting cover 300 into a combustion chamber 800 and a blast duct 600, the combustion chamber 800 is provided with a ventilation opening 850, and the combustion chamber 800 and the blast duct 600 are connected through the ventilation opening 850; the burner 700 is disposed in the combustion chamber 800, the burner 700 is disposed between the ventilation opening 850 and the air collecting cover 300, and the fan 230 can drive the fluid in the air blowing channel 600 to move through the ventilation opening 850 and move towards a direction away from the burner 700. After the blower 230 is started, the airflow is driven to flow into the wind collecting cover 300, and flows into the blower channel 600 from the wind collecting cover 300. In the continuous flowing process, the air flow passes through the ventilation opening 850 and reaches the combustion chamber 800, and finally, under the continuous driving of the fan 230, the heat in the combustion chamber 800 is driven to move towards the direction away from the fan 230, so that the effect of blowing hot air is achieved, and hot air is provided for household appliances such as the fan heater 230. The air flow generated by the fan 230 is concentrated through the air collecting cover 300, and the air flow is guided by the separation assembly 900, so that heat can be effectively limited in the combustion chamber 800, and the heat is guided away from the fan 230 by the air flow, so that the influence of the heat on the fan 230 and the driving of the fan can be effectively avoided, and the effect of protecting the fan 230 and the driving of the fan can be effectively achieved on the premise of providing hot air.
In certain embodiments, referring to fig. 2, the separation assembly 900 includes a first sleeve 400 and a second sleeve 500, the first sleeve 400 being sleeved around the second sleeve 500; the combustion chamber 800 is located in the second sleeve 500, the air blast channel 600 is located between the inner wall of the first sleeve 400 and the outer wall of the second sleeve 500, and both the first sleeve 400 and the second sleeve 500 are connected with the air collecting housing 300. The nesting of the first sleeve 400 and the second sleeve 500 can conveniently and directly divide the combustion chamber 800 and the blower duct 600, and the nested distribution can effectively reduce the overall volume, so that the household appliance using the same can be made smaller and more compact, and further, the transportation and storage processes thereof are facilitated.
It is contemplated that the combustion chamber 800 and the blower 600 may be disposed in parallel and side by side, and the specific embodiment may be adjusted accordingly according to actual needs, which is not limited herein.

Therefore, the heat is smoothly mixed at the upper portion of the combustion chamber 800, and the fan 230 outside the wind collecting cover 300 is hardly affected, so that the protection of the fan 230 and the motor driving the fan 230 can be effectively realized.
It is contemplated that the bottom of the second sleeve 500 may also be sealed by other means, such as the barrel directly contacting the inner wall of the hood 300. The specific embodiments can be adjusted according to actual needs, and are not limited herein.
In some embodiments, referring to fig. 4, the burner 700 is provided with a connection 750, the connection 750 passing through the closed bottom wall and extending outside the hood 300, the connection 750 being connected with the valve block 250. The connecting portion 750 can relatively connect the valve block 250 and the burner 700, so as to ensure that the burner 700 can obtain fuel such as fuel gas and the like distributed by the valve block 250, and further can smoothly perform combustion operation without interference trouble caused by the closed bottom wall.
Specifically, the closed bottom wall is provided with a hole site through which the connection portion 750 passes and protrudes outside the second sleeve 500 and the wind collecting housing 300.
In certain embodiments, referring to FIG. 2, the top of both the first sleeve 400 and the second sleeve 500 are in communication with the outside of the combustion chamber 800. The communication of the top makes the hot air in the combustion chamber 800 flow out from the top of the first sleeve 400 and the second sleeve 500 in time, and the interference of the hot air to the support surface during the flowing out can be effectively reduced, so that the hot air can be ensured to be smoothly discharged out of the combustion chamber 800, and the safety problem caused by overheating in the combustion chamber 800 is avoided.
In certain embodiments, referring to FIG. 2, vents 850, burner 700, and collector hood 300 are distributed in a top-to-bottom order. When the heat is blown by the ventilation opening 850, the burner 700 and the wind collecting cover 300, the heat is discharged from the ventilation opening 850 at the top, and the heat is effectively prevented from returning to the wind collecting cover 300 at the bottom, so that the heat is ensured to be difficult to influence the fan 230 at the wind collecting cover 300 smoothly, and the damage problem of the fan 230 caused by the heat is effectively avoided.
In certain embodiments, referring to fig. 2, further comprising a protective case 100, the blower 230, the wind collection housing 300, and the separation assembly 900 are all located within the protective case 100. The protection shell 100 can protect the blower 230, the wind collecting cover 300 and the separation assembly 900 inside the protection shell, so that the blower 230, the wind collecting cover 300 and the separation assembly 900 are prevented from being interfered by foreign matters such as flying dust outside during operation, and further, the home appliances such as the fan heater 230 adopting the protection shell can be ensured to operate smoothly and stably.

The sequential arrangement of the air inlet 130, the air vent 850 and the air outlet 150 can smoothly discharge heat from the top of the protective housing 100 and gradually away from the blower 230 located at the lower part thereof, so that the blower 230 can be effectively prevented from being interfered by heat generated by the burner 700, and the protection effect on the blower 230 is further realized.
In some embodiments, referring to fig. 1, the air outlets 150 are multiple and uniformly distributed along the circumferential direction of the protection shell 100. The air outlets 150 distributed around the circumferential direction of the protective housing 100 can uniformly blow out hot air from all directions of the protective housing 100, so that home appliances such as a warmer can more uniformly heat the surrounding environment, thereby effectively improving the use experience.
A second aspect of the present utility model provides an embodiment of a fan heater comprising the above blowing structure. After the blower 230 is started, the airflow is driven to flow into the wind collecting cover 300, and flows into the blower channel 600 from the wind collecting cover 300. In the continuous flowing process, the air flow passes through the ventilation opening 850 and reaches the combustion chamber 800, and finally, under the continuous driving of the fan 230, the heat in the combustion chamber 800 is driven to move towards the direction away from the fan 230, so that the effect of blowing hot air is achieved, and hot air is provided for household appliances such as the fan heater 230. The air flow generated by the fan 230 is concentrated through the air collecting cover 300, and the air flow is guided by the separation assembly 900, so that heat can be effectively limited in the combustion chamber 800, and the heat is guided away from the fan 230 by the air flow, so that the influence of the heat on the fan 230 and the driving of the fan can be effectively avoided, and the effect of protecting the fan 230 and the driving of the fan can be effectively achieved on the premise of providing hot air.
