Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1

[0032] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a mica heating frame with safety protection function. The mica heating frame with safety protection function includes a heating mechanism 100, a winding and fixing mechanism 200 and a cleaning mechanism 300. The heating mechanism 100 can realize the heating function, the winding and fixing mechanism 200 can wind, comb and fix the wire, and the cleaning mechanism 300 can clean the surface of the heating wire 102 after it has cooled down after heating.

[0033] Specifically, the heating mechanism 100 includes a bracket 101, on which a heating wire 102 is fixedly connected. The bracket 101 is a mica heating frame, and the heating wire 102 is the heating component of the mica heating frame. This is existing technology, and the working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, so it will not be described in detail here. It can realize the heating function. A connecting frame 103 is fixedly connected to the surface of the bracket 101, and a connector 104 is fixedly connected to the surface of the connecting frame 103. The connecting frame 103 provides position and support for the installation of the device. There are two connectors 104 to facilitate connection with wires.

[0034] Specifically, the winding and fixing mechanism 200 is fixedly connected to the surface of the connecting frame 103, including a circular plate 201 fixedly connected to one side of the connecting frame 103. The circular plate 201 can limit and block the wire wound on the lead screw 202. The lead screw 202 is fixedly connected to one side of the circular plate 201. The end of the lead screw 202 near the circular plate 201 can be smooth. A limiting plate 203 is sleeved on the surface of the lead screw 202.

[0035] The excess wire length connected to the connector 104 is wound around the surface of the lead screw 202, and then the limiting plate 203 is pressed by the nut 204 to fix the wire wound on the lead screw 202. This can effectively organize the wires, reduce the mess of the wires during installation, and facilitate the assembly or maintenance of the staff. At the same time, after the wires are fixed, the connection between the wires and the connector 104 is not easy to loosen when pulled. A rubber pad can be set on one side of the limiting plate 203 to increase the stability during fixing and to provide protection.

[0036] Specifically, the cleaning mechanism 300 is fixedly connected to the bracket 101 and includes a drive component 301 fixedly connected to the surface of the bracket 101. The drive component 301 can drive the connector 302 to rotate. The connector 302 is installed on the drive component 301. When the connector 302 rotates in both directions, the cleaning brush 303 can rotate in both directions. After the heating frame cools down, the surface of the heating wire 102 is cleaned to reduce the impact of dust and impurities on heat conduction and prevent local overheating or uneven heating.

[0037] Four cleaning brushes 303 are fixedly connected to the surface of the connector 302. The brushes are shaped to match the heating wire 102, and their forward and reverse rotation allows for preliminary cleaning of the surface of the heating wire 102. The cleaning brushes 303 use nylon 46 bristles, which have stronger high-temperature resistance and are suitable for scenarios requiring frequent high-temperature cleaning. They are also suitable for routine cleaning of the heating wire 102 after it has cooled down, exhibiting excellent fatigue resistance and are not easily deformed even after long-term use.

[0038] Example 2

[0039] Reference Figures 2-6This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the heating mechanism 100 also includes a protector 105 fixedly connected to the surface of the connecting frame 103. Through the setting of the protector 105, abnormal current signals can be detected and the power supply can be actively cut off to prevent the short circuit current from continuously impacting the heating wire 102 and the mica substrate, thus playing a safety protection role. A fuse 106 is fixedly connected to the connecting frame 103. Through the setting of the fuse 106, when the circuit is short-circuited due to line damage, component aging or foreign object contact, the fuse 106 will instantly melt and cut off the current through the fusible element, preventing the short circuit current from burning the mica layer or causing a fire, thus improving the safety during use. The connector 104, protector 105, fuse 106 and heating wire 102 are connected in series in a circuit through wires.

[0041] The connector 104 has a screw 107 threaded onto its surface. The screw 107 passes through the connector 104 and is threaded onto it. By wrapping one end of the wire around the screw 107 twice and then turning it with a screwdriver, pressure is applied to the wire, thus fixing the wire between the connector 104 and the screw 107. The connector 104 has a socket 112 on its surface. The socket 112 makes it easier to insert one end of the wire into the socket and then wrap the wire around the screw 107.

[0042] A ring plate 108 is fixedly connected to the bottom of the bracket 101. A connecting block 109 is fixedly connected to the inner wall of the ring plate 108. A through hole is opened on the surface of the connecting block 109, which can serve as a hole for fixing during installation.

[0043] A mounting plate 110 is fixedly connected to the connecting block 109. The mounting plate 110 has mounting holes 111 at its bottom. There are several mounting holes 111, which are arranged in a circle on the mounting plate 110. Bolts can be easily passed through the mounting holes 111 to connect with the mounting base and fix the mica heating frame.

[0044] The lead screw 202 is threaded with a nut 204. Rotating the nut 204 moves the lead screw 202, which in turn moves the limiting plate 203, applying pressure to fix the wire wound on the lead screw 202 and preventing loosening. The nut 204 is fixedly connected with a lug 205. Multiple lugs 205 are fixedly connected to the surface of one nut 204, which facilitates the rotation of the nut 204.

[0045] A limiting rod 206 is fixedly connected to one side of the circular plate 201. Two limiting rods 206 are fixedly connected to one circular plate 201, and a limiting plate 203 is sleeved on its surface. The limiting rods 206 limit the periphery of the wire wound on the lead screw 202, making it tighter during winding.

[0046] The driving component 301 includes three support rods 301a fixedly connected to the bracket 101. The motor 301b is fixedly supported by the support rods 301a. The motor 301b is fixedly connected to the support rods 301a. The output shaft of the motor 301b is fixedly connected to the connecting plate 301c. After the heating wire 102 cools down, the motor 301b can be driven to rotate the connecting plate 301c, which in turn drives the connecting component 302 and the cleaning brush 303 to rotate in both directions to clean the surface of the heating wire 102.

[0047] A positioning rod 301d is slidably connected to the connecting plate 301c, and a pull plate 301e is fixedly connected to one end of the rod. The positioning rod 301d passes through the connecting plate 301c and is inserted into the positioning hole 302c. Pulling the pull plate 301e facilitates the movement of the positioning rod 301d, causing the positioning rod 301d to disengage from the positioning hole 302c and the spring 301f to stretch, making it easy to remove the connecting piece 302. The cleaning brush 303 can then be replaced with a screwdriver.

[0048] A spring 301f is sleeved on the surface of the positioning rod 301d. The two ends of the spring 301f are fixedly connected to the surfaces of the connecting plate 301c and the pull plate 301e, respectively. The spring 301f provides power for the resetting of the positioning rod 301d and the circular plate 201 under its rebound action.

[0049] The connector 302 includes a vertical plate 302a inserted into the connecting plate 301c, a cleaning brush 303 fixedly connected to one side of the vertical plate 302a, a limiting block 302b fitted onto the upper end of the vertical plate 302a and fixedly connected to the surface of the vertical plate 302a, a positioning hole 302c opened at the upper end of the vertical plate 302a, and one end of a positioning rod 301d inserted into it. The limiting block 302b limits the vertical plate 302a inserted into the connecting plate 301c. When the limiting block 302b contacts the connecting plate 301c, the positioning rod 301d is aligned with the positioning hole 302c. When the pull plate 301e is released, the positioning rod 301d is accurately inserted into the positioning hole 302c under the action of the spring 301f, thus positioning the vertical plate 302a. The upper end of the vertical plate 302a is chamfered for easy and quick insertion into the connecting plate 301c.

[0050] In use, rotate the lug 205 to move the nut 204 off the lead screw 202, then remove the limiting plate 203 from the lead screw 202 and the limiting rod 206. Tightly wind the excess wire around the lead screw 202, and limit it with the two limiting rods 206. After winding, put the limiting plate 203 on the surface of the lead screw 202 and the limiting rod 206, thread the nut 204 onto the surface of the lead screw 202, and rotate it to apply pressure to the limiting plate 203, so that the limiting plate 203 moves and makes close contact with the surface of the wire, thereby limiting and fixing the wound wire.

[0051] After the mica heating element has been used and cooled, the forward and reverse rotation of the output shaft of motor 301b can be controlled, causing the connecting plate 301c, vertical plate 302a, and cleaning brush 303 to rotate in both directions. This cleans the surface of the heating wire 102 of dust and impurities, effectively reducing the impact of excessive adhesion on heating efficiency, minimizing safety hazards, increasing service life, and reducing the probability of accelerated aging of the heating wire 102 surface due to carbonization and corrosion of impurities at high temperatures.

[0052] In summary, the winding and fixing mechanism 200 can wind, comb, and fix the wires. Compared with the existing technology, it is less likely to cause messy wiring during installation, making it very convenient for staff to assemble or repair. The cleaning mechanism 300 can clean the surface of the heating wire 102 after it has cooled down. Compared with the existing technology, it effectively reduces the impact of excessive adhesion on heating efficiency, reduces safety hazards, improves service life, and reduces the probability of accelerated aging caused by carbonization and corrosion of impurities at high temperatures.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
