For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] Please refer to Figures 1 to 3 The embodiment of the present application provides a new integrated turbofan, which comprises an air duct 1, a fan 2 arranged at one end of the air duct 1, and a heating assembly 3 arranged inside the air duct 1 and opposite to the fan 2. One end of the air duct 1 is formed with a wind production containing groove 11 for placing the fan 2, and the other end of the air duct 1 is formed with an air outlet 12 which is contracted outward as a whole.

[0025] The fan turbine is provided with a wind channel 1, a fan 2 arranged at one end of the wind channel 1, and a heating assembly 3 arranged inside the wind channel 1 and opposite to the fan 2. The fan 2 and the wind channel 1 are integrated to achieve a close fit, and the fan 2 and the wind channel 1 are prevented from shaking and generating noise during operation of the fan 2. The integrated wind channel 1 has a smooth flow, small noise, and small wind resistance coefficient, which is beneficial to improve the wind speed. The heating assembly 3 is used to heat the wind generated by the fan 2 to achieve hot air output. One end of the wind channel 1 is formed with a wind generating accommodation groove 11 for accommodating the fan 2, and the other end of the wind channel 1 is formed with an air outlet 12 which is contracted outward as a whole. The wind generating accommodation groove 11 is circular as a whole, which is matched with the shape of the fan 2 and is beneficial to the installation of the fan 2. The other end of the wind channel 1 is provided with the air outlet 12 which is contracted outward as a whole. The structure of the air outlet 12 is contracted outward, so that the wind passing through the wind channel 1 is gathered at the air outlet 12 and then output to the outside after gathering, so as to achieve the purpose of wind concentration and guarantee the wind speed and wind force.

[0026] The specific way of air inlet of the fan turbine is shown in Figure 1 and Figure 3 The upper end of the wind generating accommodation groove 11 is provided with an air inlet 111 matched with the fan 2. The fan 2 draws air through the air inlet 111 and delivers the generated wind into the wind channel 1 to achieve wind power generation.

[0027] The specific way of air inlet of the fan turbine is shown in Figures 1 to 3 The other end of the wind channel 1 is offset to the side as a whole, and the middle part of the other end is formed with a downward recess structure 13. The air outlet 12 is arranged at the outermost side of the recess structure 13 and is contracted outward and upward as a whole. The wind channel 1 is offset to the side as a whole to achieve left and right direction guiding of the generated wind in the fan turbine. The wind channel 1 is more smooth, the wind resistance coefficient is smaller, and the noise is smaller. The specific guiding direction of left or right can be set according to the actual situation, so the specific guiding direction is not limited in the embodiment. The middle part of the other end of the wind channel 1 is formed with a downward recess shape, so that the wind to be output from the air outlet 12 in the wind channel 1 is first sunk and gathered under the guiding action of the recess structure 13, and then gathered again on the gradually contracted wind channel 1 and air outlet 12. The two structures cooperate with each other to concentrate the wind force output from the air outlet 12, and the wind speed is larger, which is beneficial to use.

[0028] The specific structure of the heating assembly 3 is shown in Figure 3As shown, the heating assembly 3 comprises a shell 31 fixed in the middle of the air duct 1, two groups of mica sheets 32 arranged diagonally on the shell 31, and a spring 33 penetrating through the outer sides of the two groups of mica sheets 32 and bent into a cuboid shape. The shell 31 is a hollow shell 31 with its side fixed tightly to the air duct 1 and its middle hollow and radially aligned with the air duct 1, so that the air delivered from the fan 2 is heated by the mica sheets 32 via the hollow position. The spring 33 penetrates through the outer sides of the two groups of mica sheets 32 and surrounds the periphery of the mica sheets 32, so that the position of the mica sheets 32 is fixed and the mica sheets 32 are buffered from shaking, preventing the fragile mica sheets 32 from being shaken and damaged when the fan 2 is operating.

[0029] For the specific structure of the mica sheets 32, as shown in Figure 3 The middle of the mica sheet 32 is formed with an embedding groove 321 for cross embedding, and the two groups of mica sheets 32 are embedded with each other via the embedding groove 321, forming an X-shaped structure with a larger heating area and being more conducive to heating the air delivered from the fan 2 and improving the heating efficiency. The outer side of the mica sheet 32 is formed with a plurality of hook grooves 322 for the spring 33 to penetrate through, and the spring 33 penetrates through the hook grooves 322 in sequence, so that the spring 33 is embedded between the mica sheets 32, clamping and fixing the mica sheets 32 and preventing the mica sheets 32 from breaking.

[0030] For the specific structure of the air duct 1, as shown in Figure 3 The air duct 1 comprises an upper shell 14 and a lower shell 15 buckled on the upper shell 14, and the air inlet 111 is formed on the upper surface of the upper shell 14. The structure of the upper shell 14 and the lower shell 15 buckled on each other facilitates installation and disassembly, improves the assembly speed, and is more conducive to production and maintenance.

[0031] For the specific way of buckling between the upper shell 14 and the lower shell 15, as shown in Figure 3 The two sides of the upper shell 14 are respectively formed with a mounting and fixing block 141 radially protruding outward, and the two sides of the lower shell 15 are respectively formed with a mounting seat 151 extending upward for the mounting and fixing block 141 to be embedded. The mounting seat 151 is a hollow cuboid extending upward. When the upper shell 14 and the lower shell 15 need to be buckled, the mounting and fixing block 141 needs to be embedded in the hollow part of the hollow cuboid, and the two are tightly combined, so that the upper shell 14 and the lower shell 15 are buckled on each other and prevented from loosening.

[0032] In order to facilitate the embedding of the mounting and fixing block 141 in the mounting seat 151, as shown in Figure 3As shown, the lower end surface of the mounting fixed block 141 is formed with a mounting guide surface 1411 extending obliquely from the upper outside to the lower inside, when the mounting fixed block 141 needs to be inserted into the hollow part of the hollow cuboid, the mounting guide surface 1411 first contacts the hollow part of the hollow cuboid, and under the guidance of the mounting guide surface 1411, the mounting fixed block 141 is more easily and accurately inserted into the hollow part of the hollow cuboid, thereby improving the speed and accuracy of the mounting fixed block 141 mounted on the mounting seat 151, and further improving the efficiency and accuracy of the upper shell 14 buckled on the lower shell 15.

[0033] In order to better install the whole turbofan, as shown, Figures 1 to 3 As shown, at least one screw through seat 16 is formed on the both sides of the air duct 1, which protrudes outward. By screwing the external screw through the screw through seat 16, the whole turbofan can be fixed on the required workpiece for assembly, further improving the practicability of the turbofan, and being more convenient for people to use.

[0034] It should be noted that the integrated novel turbofan disclosed in the utility model is improved in specific structure, and the specific control mode is not the innovation point of the utility model. The fan, mica sheet, spring, screw and other components involved in the utility model can be general standard components or components known to those skilled in the art, and the structure, principle and control mode thereof are known to those skilled in the art through technical manuals or through conventional experimental methods.

[0035] The above is only a preferred embodiment of the utility model, and does not limit the technical scope of the utility model, so other structures obtained by using the same or similar technical features as the above-mentioned embodiments of the utility model are within the protection scope of the utility model.
