Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0026] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0027] Please refer to Figure 1-Figure 4As shown, the utility model discloses a ceramic heating element hair dryer, including a housing 10, a ceramic heating component 20, a motor 30, a control board 40 and a fan blade component 50. The ceramic heating component 20, the motor 30, the fan blade component 50 and the control board 40 are all arranged in the housing 10. The motor 30 is transmission-connected to the fan blade component 50, and the control board 40 is electrically connected to the motor 30 and the ceramic heating component 20. The ceramic heating component 20 includes a first electrode 21, a second electrode 22, a ceramic heating element 23, a first bracket 24 and a second bracket 25. The shape of the ceramic heating element 23 is cylindrical, and the ceramic heating element 23 includes a first end face 231 and a second end face 232 that are arranged oppositely, the first electrode 21 is attached to the first end face 231, the second electrode 22 is attached to the second end face 232, and the first bracket 24 and the second bracket 25 clamp the first electric plate, the ceramic heating element 23 and the second electrode 22. In this embodiment, the first electrode 21 and the second electrode 22 are both wavy annular parts. In the past, our company selected the first electrode and the second electrode to be made of a harder metal. Since the ring size of the first electrode 21 and the second electrode is large, unstable contact and excessive impact current will occur, which poses a risk of fire. Therefore, this application improves the first electrode 21 and the second electrode 22, and improves the first electrode 21 and the second electrode 22 into a wave shape, and then clamps them through the first bracket 24 and the second bracket 25. Since the wave shape has a certain elastic force, the contact is more uniform and stable, avoiding the unstable contact, making the contact between the first electrode 21 and the second electrode 22 and the ceramic heating element 23 more stable, avoiding the occurrence of the above situation, and improving the safety performance.

[0028] In this embodiment, the first bracket 24 and the second bracket 25 are both annular in shape, the first bracket 24 is provided with a first groove portion (not shown in the figure), and the second bracket 25 is provided with a second groove portion 251, the position of the first groove portion corresponds to the position of the second groove portion, and the first groove portion and the second groove portion are combined to form a space for clamping the ceramic heating element 23, the first electrode 21 and the second electrode 22, and a plurality of screws are passed through the first bracket 24 and the second bracket 25 to fix the ceramic heating component 20 as a whole. Since the first electrode 21 and the second electrode 22 are arranged in a wavy shape, the first electrode 21 and the second electrode 22 have a certain elasticity. After the first bracket 24 and the second bracket 25 clamp the first electrode 21, the ceramic heating element 23 and the second electrode 22, it can ensure that the contact between the first electrode 21 and the ceramic heating element 23, and the contact between the second electrode 22 and the ceramic heating element 23 is more uniform and stable, avoiding the situation of excessive impact current, and improving the safety performance of the device.

[0029] In some embodiments, in order to further increase the contact effect, the first electrode 21 and the second electrode 22 are both made of copper, so the first electrode 21 and the second electrode 22 are softer. After being clamped by the first bracket 24 and the second bracket 25, the contact effect between the first electrode 21, the second electrode 22 and the ceramic heating element 23 is better.

[0030] In some optional embodiments, the first electrode 21 and the second electrode 22 each include a connected ring body portion 211 and a connecting wall portion 212, and the connecting wall portion 212 extends out of the first bracket 24, so as to be connected to the control board 40 through a wire. Two through-hole portions 241 are provided on the first bracket 24, and the connecting wall portion 212 passes through the through-hole portions 241 and is arranged toward the control board 40, so as to facilitate the connection of the connecting wall portion 212 and the control board 40 through a wire.

[0031] In this embodiment, the hair dryer further includes a push plate switch 60, which is connected to the control board 40. The size of the blowing and the temperature of the outlet air are controlled by the push plate switch 60. The housing 10 includes a main housing 11 and a handle housing 12 connected to each other. The push plate switch 60 is disposed in the handle housing 12 and exposed to the outside for external adjustment by the user. The ceramic heating component 20, the motor 30, and the fan blade component 50 are all disposed in the main housing 11.

[0032] The housing 10 includes an air inlet 13 and an air outlet 14, wherein the air outlet 14 is disposed on the main housing 11, and the air inlet 13 is disposed on the handle housing 12. In other embodiments, the number of the air inlet 13 can be two, wherein one of the air inlet 13 is disposed on the handle housing 12, and the other of the air inlet 13 is disposed on the main housing 11, and the other of the air inlet is disposed at an end of the main housing 11 away from the air outlet.

[0033] 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 shell 11. The air collecting nozzle 70 can make the wind force of the air out more concentrated, thereby improving the drying effect.

[0034] In this embodiment, the fan blades include 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.

[0035] In this embodiment, a plurality of triangular openings are evenly arranged on the ceramic heating element 23. Compared with the honeycomb-shaped openings of the original solution, the triangular openings improve the structural strength and can obtain a higher rated power.

[0036] 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.
