Example 1:

as shown in fig. 1, a novel drying hot air blower is characterized by comprising a hot air blower main body 1, wherein an air duct 4, an air inlet 5 and an air outlet 6 are arranged on the hot air blower main body 1, and the air duct 4 comprises an air inlet duct 401, an air lifting duct 402, a first auxiliary heating air duct 403, a air descending duct 404, a second auxiliary heating air duct 405 and an air outlet duct 406 which are sequentially communicated; a first heater 2 is arranged outside the air heater main body 1; a second heater 3 is arranged above the outer part of the air heater main body 1; the air inlet 5 and the air outlet 6 are respectively communicated with the air duct 4.

The diameter of the pipeline of the ascending air duct 402 is larger than that of the air outlet duct 406, and the diameter of the pipeline of the air outlet duct 406 is larger than that of the descending air duct 404; the air inlet duct 401 is communicated with a first auxiliary heating air duct 403 through an ascending air duct 402; the first auxiliary heating air duct 403 is communicated with the second auxiliary heating air duct 405 through a descending air duct 404; the second auxiliary heating air duct is communicated with the air outlet duct 406. The heating pipes 201 of the first heater 2 penetrate through the air heater main body 1 and extend into the air inlet duct 401, and are close to the air inlet 5. The first heater 2 is disposed outside the air heater main body 1 and closely attached to the air inlet duct 401 and the second auxiliary heating air duct 405. The second heater 3 is arranged outside the air heater main body 1 and closely attached to the upper part of the first auxiliary heating air duct 403.

The working process of the embodiment: the first heater 2 is opened, after the air in the air inlet channel 401 is heated by the heating pipe 201, the air is accumulated in the first auxiliary heating air channel 403 through the air ascending channel 402, the hot air forms a pressure difference with the second auxiliary heating air channel 405 in the first auxiliary heating air channel 403, the hot air flows to the second auxiliary heating air channel through the air descending channel 404, at this time, because the first heater 2 is already opened and the diameter of the pipeline of the air descending channel 404 is thinner as shown in the figure, the hot air flows out through the air outlet channel 406 through the air outlet 6 at an accelerated speed due to the pressure difference, when the temperature of the hot air needs to be raised continuously or the hot air flow rate of the air outlet 6 needs to be accelerated, the second heater 3 is opened to heat the first auxiliary heating air channel 403, and the flow rate is accelerated by increasing the temperature difference.

While one embodiment of the present invention has been described in detail, the present invention is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
