[0001] The present application relates to the technical field of hair dryers, and in particular to a heating bracket and a straight-tube hair dryer. Background Art

[0002] The heating components (heating brackets) used in the straight-tube hair dryers currently on the market require many parts. The mica sheets in the heating components require connectors to complete assembly. The existence of connectors leads to many assembly steps for the heating components, low assembly efficiency, and increased production costs of the components and assembly costs of the components.

[0003] In order to solve the above problems, it is urgently necessary to provide a heating assembly that does not require connectors and can be quickly assembled. Utility Model Content

[0004] In order to solve the above problems, the present application provides a heating bracket and a straight-tube hair dryer, which are cleverly designed and simple in structure. The connection between the mica sheets in the heating bracket does not require a connector, and the mica sheets are connected by interpenetrating and plugging each other, which simplifies the assembly method of the mica sheets, saves assembly steps, improves assembly efficiency, and increases production revenue. The technical solutions adopted in the present application are as follows:

[0005] A heating bracket comprises: a plurality of mica sheets, wherein the plurality of mica sheets are inserted and connected with each other to form the heating bracket.

[0006] In this application, the connection between the mica sheets of the heating bracket does not require connectors. The mica sheets are connected by interpenetrating and snapping each other together, which simplifies the assembly method of the mica sheets, saves assembly steps, improves assembly efficiency, and increases production revenue.

[0007] In some embodiments, the number of the mica sheets is 3, which are respectively set as the first sheet, the second sheet and the third sheet;

[0008] The first sheet is provided with a first insertion seam, which is provided at a middle position of the width of the first sheet and extends along the length direction of the first sheet, one end of the first insertion seam does not penetrate the first sheet, and the other end thereof penetrates the first sheet;

[0009] The second sheet is provided with second insertion seams at both ends along the length direction, and the second insertion seams are provided in the middle of the width of the second sheet and extend along the length direction of the second sheet;

[0010] The third sheet is provided with a third insertion seam, which is provided at the middle position of the width of the third sheet and extends along the length direction of the third sheet, one end of the third insertion seam does not penetrate the third sheet, and the other end penetrates the third sheet;

[0011] The first sheet, the second sheet and the third sheet are assembled into the heating bracket in a positive or reverse order, and the end of the first sheet not penetrated by the first insertion seam is simultaneously inserted into the second insertion seam and the third insertion seam at one end of the second sheet, and the end of the third sheet not penetrated by the third insertion seam is simultaneously inserted into the second insertion seam and the first insertion seam at the other end of the second sheet.

[0012] By setting three mica sheets, compared with setting two mica sheets, the roundness of the heating bracket can be improved, and a longer heating wire can be wound around the heating bracket. Compared with setting four or more mica sheets, the number of mica sheets can be saved, and some mica sheet insertion and clamping processes can be saved. At the same time, the production cost and assembly cost of the mica sheets can also be saved, and too many mica sheets can be prevented from interfering with the airflow, generating greater wind noise and weakening the airflow velocity.

[0013] In some embodiments, a fuse and an over-temperature protection switch are further included, and both the fuse and the over-temperature protection switch are mounted on the mica sheet.

[0014] By setting the fuse and the over-temperature protection switch at the same time, double protection can be formed to improve safety.

[0015] In some embodiments, a thermistor is further included, and the thermistor is mounted on the mica sheet and located at the air outlet end of the heating bracket.

[0016] Thermistors are temperature sensors. The resistance of a thermistor changes with temperature. By detecting the change in the resistance or current of the thermistor, the ambient temperature can be obtained, and the ambient temperature can be monitored so that the ambient temperature can be controlled and adjusted. If a thermistor is set up on the basis of a fuse and an over-temperature protection switch, triple protection can be formed to further improve safety.

[0017] In some embodiments, the three mica sheets are provided with at least two clearance openings, and the fuse and the over-temperature protection switch are respectively installed in two different clearance openings.

[0018] By setting a clearance opening and installing the fuse and the over-temperature protection switch in the clearance opening, the difficulty of installing the fuse and the over-temperature protection switch can be reduced, so that the two can better contact the airflow and fully play their role, and at the same time, the interference of the fuse and the over-temperature protection switch on the airflow can be reduced.

[0019] In some embodiments, the second piece is provided with two said make way openings, the two said make way openings of the second piece are separated by a connecting rib, and the fuse and the over-temperature protection switch are respectively installed in the two said make way openings of the second piece.

[0020] The second plug-in seam on the second piece is arranged at both ends of the second piece in the length direction, and no second plug-in seam is arranged in the middle part of the length direction of the second piece. Compared with the first piece and the third piece, the second piece is stronger. The fuse and the over-temperature protection switch are installed on the second piece, which reduces the risk of damage to the first piece and the third piece and improves the overall reliability of the heating bracket.

[0021] In some embodiments, the heating bracket is surrounded by a plurality of circles of heating wires.

[0022] In some embodiments, a guide cap is provided at one end of the heating bracket, and a plurality of slots are provided on a side of the guide cap close to the mica sheet, and one end of the three mica sheets close to the guide cap are respectively inserted into the corresponding slots.

[0023] By setting a guide cap, the interference of the mica sheet on the airflow can be reduced, the wind noise generated when the airflow passes through the heating bracket can be reduced, and the flow rate of the airflow can be increased; the mica sheet is inserted into the card slot of the guide cap, which can enhance the integrity of the heating bracket, improve the overall strength of the heating bracket, and make the mica sheets of the heating bracket less likely to disperse.

[0024] In some embodiments, the guide cap is provided with at least two hooks, and the three mica sheets are provided with engaging holes adapted to the hooks, and the hooks are engaged in the corresponding engaging holes.

[0025] By providing the hooks and the connecting holes, the connection stability between the guide cap and the mica sheet can be enhanced, and the risk of the guide cap falling off during use can be reduced.

[0026] In some embodiments, the heating support is covered with a mica tube, and at least one mica sheet is clamped to the mica tube.

[0027] By providing a mica tube, the heat generated by the heating wire can be prevented from causing damage to the hair dryer housing and the user, while also reducing the loss of heat generated by the heating wire and improving the heating effect on the airflow; the mica tube is connected to the mica sheet by a snap-on method, which is simple and convenient.
