[0024] Please refer to Figure 1-Figure 3As shown, the utility model discloses an improved ceramic heating element hair dryer, comprising a housing 10, a ceramic heating component 20, a motor 30, a control board 40 and a fan blade component 50, wherein the ceramic heating component 20, the motor 30, the control board 40 and the fan blade component 50 are all arranged in the housing 10. The motor 30 is transmission-connected to the fan blade component 50. The control board 40 is electrically connected to the motor 30 and the ceramic heating component 20. The ceramic heating element 20 includes a ceramic heating element 21, a fixing member 22, a first electrode 23, and a second electrode 24. The ceramic heating element 21 is cylindrical and includes a first end face 211 and a second end face 212 opposite to each other. The center of the ceramic heating element 21 is provided with a through hole 213. The first electrode 23 is attached to the first end face 211, and the second electrode 24 is attached to the second end face 212. The fixing member 22 is provided in the through hole 213, and the fixing member 22 passes through the first electrode 23, the ceramic heating element 21, and the second electrode 24 in sequence to fix the first electrode 23 and the second electrode 24 on the ceramic heating element 21. The first electrode 23 and the second electrode 24 have the same shape, and both include an annular fitting portion 231, which is attached to the first end face 211 and the second end face 212. The diameter of the annular fitting portion 231 is 1 / 8-1 / 5 of the diameter of the first end face 211 and the second end face 212. Compared with our company's original technical solution, the area where the first electrode 23 and the second electrode 24 of this application are attached to the ceramic heating element 21 is reduced, which reduces the occurrence of unstable contact and excessive impact current, and avoids the undesirable phenomenon of fire. In addition, this application does not set two brackets to fix the first electrode 23 and the second electrode 24. The structure is simpler than the original solution, reducing the assembly cost.

[0025] In this embodiment, the first electrode 23 and the second electrode 24 also include a connecting wall portion 232, which is connected to the annular fitting portion 231. The connecting wall portion 232 is used to connect the wires, and connect the first electrode and the control board 40, as well as the second electrode 24 and the control board 40 through the wires.

[0026] The first end surface 211 is arranged toward the control board 40, and the second end surface 212 is arranged away from the control board 40. The ceramic heating element 21 also includes a strip-shaped hole portion 214, and the connecting wall portion 232 of the second electrode 24 passes through the strip-shaped hole portion 214 and points to the control board 40. Through the above structure, the connecting wall portion 232 of the second electrode 24 and the connecting wall portion 232 of the first electrode 23 can both point to the control board 40, so as to facilitate the connection between the second electrode 24 and the control board 40.

[0027] The hair dryer of the present application further comprises a push plate switch 60, which is connected to the control panel 40. By controlling the push plate switch 60, the size of the hair dryer and the temperature of the air outlet can be controlled.

[0028] The housing 10 includes a main housing 11 and a handle housing 12 which are connected to each other. The push plate switch 60 is arranged in the handle housing 12 . The ceramic heating component 20 , the motor 30 , and the fan blade component 50 are all arranged in the main housing 11 .

[0029] The housing 10 includes two air inlets 13 and an air outlet 14, wherein the air outlet 14 is disposed at one end of the main housing 11, wherein one air inlet 13 is disposed at the other end of the main housing 11, and the other air inlet 13 is disposed on the handle housing 12. By providing two air inlets 13, the wind portion of the housing 10 can be fully cooled.

[0030] In an optional embodiment, the hair dryer of the present application further includes an air collecting nozzle 70, which is installed at the air outlet 14 of the main housing 11. The air collecting nozzle 70 can make the wind force of the air out more concentrated, thereby improving the drying effect.

[0031] In this embodiment, the fan blade assembly 50 includes a plurality of fan blades. The overall shape of the fan blade assembly 50 composed of the plurality of fan blades is hemispherical, which can make the wind more uniform and also increase the maximum wind speed.

[0032] In this embodiment, the fixing member 22 is a bolt 221 and a nut 222 made of insulating material. The fixing member 22 is made of insulating material to insulate the first electrode and the second electrode 24.

[0033] In this embodiment, a plurality of triangular through holes are evenly arranged on the ceramic heating element. Compared with the honeycomb-shaped through holes of the original solution, the triangular through holes improve the structural strength and can obtain a higher rated power.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
