Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to a ceramic heating body with multiple groups of heating units. Background Art

[0002] Electronic cigarettes are an electronic product that imitates cigarettes. Although electronic cigarettes do not contain tar, they still contain many other carcinogens and have the same appearance, smoke, taste and feel as cigarettes. Most electronic cigarettes use ceramic heating units due to their corrosion resistance, high temperature resistance, long life, high efficiency and energy saving, uniform temperature, and good thermal conductivity.

[0003] After searching the patent document with the publication number CN219537491U, the patent document discloses "a ceramic heating element with multiple groups of heating units, by arranging multiple groups of heating units in the ceramic element, so as to realize multiple combined working modes of the multiple groups of heating units, for example, one group of heating units switches to another group of heating units after heating for a period of time, and the multiple groups of heating units are switched to use in turn, so as to evenly distribute the workload of each heating unit, reduce the heating time of the heating unit, thereby reducing the carbon deposition and blockage of the central airway of the heating unit, and reduce the risk of burning the e-liquid";

[0004] When the above-mentioned device is in operation, one group of heating units will be switched to another group after operating for a period of time, thereby avoiding the problems caused by long-term operation of one group of heating units. However, when switching to another group of heating units for operation, the heating temperature will fluctuate greatly, which can easily affect the heating effect. Utility Model Content

[0005] The purpose of the utility model is to provide a ceramic heating element with multiple groups of heating units in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A ceramic heating element with multiple groups of heating units, comprising a mounting tube, a heating mechanism for heating treatment is installed inside the mounting tube, and a starting mechanism for energizing the heating structure;

[0008] The starting mechanism includes three junction boxes, all of which are installed in the middle position inside the installation cylinder. A power supply is installed at the lower end of the junction box, a switch button is installed at the lower end of the power supply, a low-speed motor is installed at the bottom of the installation cylinder, a notched turntable is fixed at the output end of the low-speed motor, and two convex plates are fixed at the upper end of the notched turntable.

[0009] Preferably, the upper end surface of the notched rotating disk is provided with a through groove having an area of ​​one third of its upper end, and one end of the convex plate is rounded.

[0010] Preferably, the lowermost end of the switch button when no force is applied is lower than the uppermost end of the convex plate, and the two convex plates are located directly below two of the power supplies.

[0011] Preferably, the starting mechanism further comprises a limiting ring, which is rotatably connected to the outer ring of the notched turntable and is fixed to the inner wall of the mounting tube.

[0012] Preferably: the heating mechanism comprises a ceramic block, which is fixed to the inner wall of the upper end of the mounting tube, and the upper end surface of the ceramic block is provided with three through holes, each of which is provided with a heating wire, both ends of the heating wire are electrically connected with pins, and the bottom of the pins is connected to a junction box.

[0013] Preferably, the inner diameter of the upper end of the through hole is smaller than the inner diameter of the inner part thereof.

[0014] The beneficial effects compared with the prior art are as follows:

[0015] When the device is in operation, the uppermost end of the convex plate is higher than the lowermost end of the switch button and the two convex plates are respectively located directly below two of the power supplies. When the low-speed motor drives the notched turntable to rotate counterclockwise, one of the convex plates can first contact the unturned switch button, so that the power supply and the corresponding group of heating structures are energized and start preheating. At the same time, the other convex plate will separate from the originally squeezed switch button as the notched turntable rotates, so that the group of heating structures corresponding to the power supply is powered off. Then, the convex plate will support the switch button originally supported by the other convex plate, so that this group of heating structures continues to generate heat. In this way, the heating condition inside the device will not change significantly when the heating unit is switched, thereby avoiding the effect of heating being affected by the large temperature rise and fall.

[0030] The heating mechanism includes a ceramic block 2, which is fixed on the inner wall of the upper end of the mounting tube 1. Three through holes 21 are opened on the upper end surface of the ceramic block 2. The inner circle diameter of the upper end of the through hole 21 is smaller than the inner circle diameter of its interior. A heating wire 22 is installed inside each through hole 21, and pins 23 are electrically connected to both ends of the heating wire 22.
