The two fixing portions 112 are respectively located in the length direction of the heating tube 13 for fixing the position of the heating tube 13 in the horizontal direction.

Please refer to Figures 1 and 2. The wiring box 2 is in the form of a rectangular parallelepiped, and the wiring box 2 is hollow. A control box 21 is provided in the wiring box 2. The control box 21 is used to control the opening and closing of the heating tube 13. In one embodiment, the control box 21 is fixed in the wiring box 2 body by fixing bolts. In other embodiments, the control box 21 can also be fixed by embedding or gluing. In one embodiment, please refer to Figure 2. The wiring box 2 includes a bottom plate 22 and a fixing shell 23, wherein the bottom plate 22 is located above the heater body 1 and is fixed to the heater body 1. In one embodiment, the fixing shell 23 is covered above the bottom plate 22. A plurality of threaded holes 231 are provided on the fixing shell 23 and the bottom plate 22. A limiting bolt (not shown in the figure) is fixed in the threaded hole 231. The limiting bolt passes through the cover shell 11 and is threadedly fixed to the fixing shell 23 and the bottom plate 22. Two through holes 232 are disposed on the top of the fixing shell 23 , and the through holes 232 are used for the fall protection mechanism 3 to pass through.

A hanging chain 24 is provided above the wire box 2. In one embodiment, two hanging chains 24 are provided. The two hanging chains 24 are respectively fixed to the two fall protection mechanisms 3 to ensure the vertical position of the wire box 2.

Please refer to Figures 2 and 3. There are two drop protection mechanisms 3. The two drop protection mechanisms 3 respectively include a hanging ring 31, a rotating handle 32 and a micro switch 33. In one embodiment, the hanging ring 31, the rotating handle 32 and the micro switch 33 are arranged in sequence along the length direction. The hanging ring 31 is in the shape of a long strip. The hanging ring 31 is inserted into the through hole 232. One end of the hanging ring 31 protruding from the through hole 232 is provided with a hanging ring 31 hole. The setting of the hanging ring 31 hole facilitates the mutual fixation of the hanging chain 24 and the hanging ring 31. In one embodiment, a stopper 312 is provided on the lifting ring 31, and the stopper 312 abuts against the inner wall of the fixed shell 23 to prevent the lifting ring 31 from sliding outward; a rack 313 is provided on one side wall of the lifting ring 31 in the vertical direction. In one embodiment, the rack 313 and the lifting ring 31 are integrally formed. The rotating handle 32 includes a rotating shaft 321 and an extension arm 322, wherein the rotating shaft 321 is rotatably arranged. In one embodiment, a fixed plate 221 is provided on the bottom plate 22, and the fixed plate 221 is corresponding to the rotating shaft 321. Each rotating shaft 321 corresponds to two fixed plates 221. The fixed plates 221 are located at both ends of the rotating shaft 321 in the axial direction to fix the rotating shaft 321, and the rotating shaft 321 is rotatably arranged on the fixed plate 221. The rotating shaft 321 is provided with spur teeth 3211, which are meshed with the rack 313. When the rack 313 slides in the vertical direction, it drives the rotating shaft 321 to rotate. The extension arm 322 is located on the rotating shaft 321 and rotates synchronously with the rotating shaft 321. In one embodiment, when the lifting ring 31 is at the highest point, that is, when the stopper 312 abuts against the inner wall of the fixed shell 23, the end of the extension arm 322 abuts against the contact of the micro switch 33 to keep the micro switch 33 in an energized state. In one embodiment, a torsion spring 3212 is also provided in the rotating shaft 321. The torsion spring 3212 is fixed on the rotating shaft 321, and the torsion spring 3212 is used to press the extension arm 322 to rotate it upward.

The micro switch 33 is vertically arranged, and the contact of the micro switch 33 is arranged to point to the rotating handle 32. The rotating handle 32 is pressed against the contact so that the micro switch 33 is in a power-on state. The micro switch 33 is connected to the control box 21. When the micro switch 33 is powered on, the switch on the control box 21 can control the opening and closing of the heating tube 13. When the micro switch 33 is powered off, the control box 21 will also control the closing of the heating tube 13.

Working principle:

Please refer to FIG. 3 and FIG. 4 . In a normal state, the lifting chain 24 suspends the lifting ring 31 to keep it at the highest point. The lifting ring 31 is fixed in position by the tension of the lifting chain 24 . The position of the extension arm 322 is fixed by the mutual meshing between the rack 313 and the spur gear 3211 . Thus, the extension arm 322 and the contact of the micro switch 33 are kept in contact with each other, and the micro switch 33 remains energized.

When the hanging ring 31 falls off or the heater body 1 falls downward, the hanging ring 31 loses the pulling force of the hanging chain 24, and slides downward under the action of its own gravity and the elastic force of the torsion spring 3212, while the spur gear 3211 rotates synchronously, and the extension arm 322 is lifted upward to disconnect the contact of the micro switch 33. The micro switch 33 is in a power-off state, and the control box 21 stops supplying power to the heating tube 13, and the heating tube 13 stops working.

The hanging heater with a drop protection mechanism provided in the present application has a drop protection mechanism 3. When the hanging ring 31 falls off or the product is in a falling state, the rotation of the rotating shaft 321 drives the rotation of the extension arm 322, so that the micro switch 33 is powered off, so as to quickly cut off the power supply of the heating tube 13 and prevent the device from continuing to operate, thereby reducing the degree of damage and ensuring the safety of the user. The drop protection mechanism 3 provided in the present application improves the stability and reliability of the heater, allowing users to enjoy warmth with peace of mind.
