[0029] Please refer to Figures 1 to 3 The following describes a heating device 100 according to an embodiment of the present utility model.

[0030] Please refer to Figures 1 to 3This application provides a heating device 100, which includes a sleeve 10 and a heating component 20. The sleeve 10 is in the shape of a bent tube and has a hollow structure. The heating component 20 extends in a straight direction and is disposed inside the sleeve 10. The two ends of the heating component 20 extend to the beginning and end ends of the sleeve 10, respectively. The sleeve 10 includes an upper shell 11 and a lower shell 12 connected to each other. At least one of the upper shell 11 and the lower shell 12 is provided with a positioning structure for positioning the heating component 20.

[0031] In this application, the heating device 100 contains only one heating element 20. During installation, the heating element 20 is positioned using the positioning structure of the upper housing 11 and / or the positioning structure of the lower housing 12, allowing the heating element 20 to be accurately installed within the upper housing 11 or the lower housing 12. Finally, the upper housing 11 and the lower housing 12 are assembled together to complete the assembly of the heating device 100. In the prior art, a curved sleeve is used to cooperate with multiple heating elements to form a heating device. Since the heating elements need to cooperate with the sleeve, their outer contours are arc-shaped, and multiple heating elements are arranged in an arc shape within the sleeve. However, this application uses a curved sleeve 10 to cooperate with a single straight heating element 20 to form the heating device 100, which reduces the number of heating elements 20 required for assembly, greatly improving the assembly efficiency of the heating device 100, thereby improving the assembly efficiency of the hair dryer, and consequently increasing the production efficiency of the hair dryer, significantly improving the production process.

[0032] It is understandable that since the sleeve 10 is a hollow structure, the sleeve 10 has two openings, and the positions of the two openings on the sleeve 10 are the beginning and end ends of the sleeve 10.

[0033] In some embodiments, please refer to Figure 1 The inner surface of the upper housing 11 is provided with an upper positioning groove 111, which serves as a positioning structure. Specifically, the inner surface of the upper housing 11 is the surface of the upper housing 11 facing the heating element 20. During installation, the heating element 20 is simply inserted into the positioning groove. Compared to setting protrusions on the inner surface of the upper housing 11 to position the heating element 20, using a positioning groove reduces manufacturing difficulty.

[0034] In some embodiments, please refer to Figures 1 to 3 There are two upper positioning grooves 111, which are arranged at intervals and located at the beginning and end of the upper housing 11, respectively. It can be understood that the beginning and end of the upper housing 11 are the same as the beginning and end of the sleeve 10. This arrangement helps improve the installation accuracy of the heating element 20, thereby further improving the production efficiency of the heating device 100. Furthermore, in this embodiment, the two upper positioning grooves 111 are arranged at intervals, rather than a single positioning groove extending along the beginning and end of the upper housing 11, which helps reduce the complexity of the mold structure and thus lowers production costs.

[0035] In some embodiments, please refer to Figures 1 to 3 The lower housing 12 has a lower positioning groove 121, which serves as a positioning structure. Specifically, the inner surface of the lower housing 12 is the surface of the lower housing 12 facing the heating element 20. Based on the upper positioning groove 111 provided in the upper housing 11, the lower positioning groove 121 is further provided on the inner surface of the lower housing 12. This arrangement improves the stability of the heating element 20 within the sleeve 10 and reduces the degree of shaking of the heating element 20 within the sleeve 10.

[0036] In some embodiments, please refer to Figures 1 to 3 There are two lower positioning grooves 121, which are arranged at intervals and located at the beginning and end of the lower housing 12, respectively. It can be understood that the beginning and end of the upper housing 11 are the beginning and end of the sleeve 10. This arrangement can further improve the stability of the heating element 20 within the sleeve 10.

[0037] In some embodiments, please refer to Figures 1 to 3 The upper housing 11 and the lower housing 12 are snapped together. Specifically, the upper housing 11 is provided with a boss 112, and the lower housing 12 is provided with a slot 122 for snapping with the boss 112. Compared with the screw fastening method, the snap-fit ​​connection method can further improve the assembly efficiency of the heating device 100, thereby improving the production efficiency of the heating device 100.

[0038] In some embodiments, please refer to Figures 1 to 3 The lower housing 12 has a protrusion 123 on its surface near the upper housing 11, and a slot 122 is formed in the protrusion 123. The outer surface of the upper housing 11 has a receiving groove 113 for accommodating the protrusion 123, and a boss 112 is disposed in the receiving groove 113, with the boss 112 located at the end of the receiving groove near the lower housing 12. When the upper housing 11 and the lower housing 12 are engaged, the protrusion 123 enters the receiving groove. When the boss 112 is engaged in the slot 122, the protrusion 123 is located in the receiving groove. This arrangement reduces the volume of the heating device 100, thereby reducing the space occupied by the heating device 100.

[0039] In some embodiments, please refer to Figures 1 to 3A positioning element 114 is provided on the surface of the upper housing 11 near the lower housing 12, and a mounting positioning groove 124 for accommodating the positioning element 114 is provided on the surface of the lower housing 12 near the upper housing 11. Specifically, both ends of the positioning element 114 extend to the beginning and end ends of the upper housing 11, and both ends of the mounting positioning groove 124 extend to the beginning and end ends of the lower housing 12, penetrating both end faces of the lower housing 12. The mounting positioning groove 124 is used to position the positioning element 114. The arrangement of the positioning element 114 and the mounting positioning groove 124 can further improve the assembly efficiency of the heating device 100, thereby improving the production efficiency of the heating device 100.

[0040] It is understood that the heating element 20 includes a heating frame and heating wires wound around the heating frame, wherein the heating frame extends in a straight line, that is, the heating frame is in a straight line overall, and the heating wires are wound around the heating frame in a straight line. During installation, the heating frame is installed in the upper positioning groove 111 and / or the lower positioning groove 121. Since the heating frame and heating wires are both prior art, and this application does not improve upon them, they will not be described in detail here.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
