[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0024] Reference Figure 1-Figure 3 The electronic atomizer with a ceramic center rod provided by the utility model includes a nozzle 1, a ceramic center rod 2, an oil cup 3, a base 4 and an electrode 5. The head of the ceramic center rod 2 is in interference connection with the nozzle 1, the tail of the ceramic center rod 2 is in interference connection with the oil cup 3, the base 4 is sleeved on the end of the oil cup 3, and the electrode 5 is clamped with the base 4. The application of the ceramic center rod 2 is also more conducive to the reliability of the light riveting connection, because the surface roughness of the unglazed ceramic itself is relatively large, and it has good thermal stability and low expansion rate. When lightly riveted with the plastic oil 3 and the nozzle 1, only a small interference amount and a depth of several millimeters are required to press, and it will not fall off even if high temperature is generated during operation. The ceramic center rod 2 and the nozzle usually only need an interference amount of 0.05 to 0.08 mm. The smaller the interference amount, the smaller the riveting force, so it can be pressed in without the help of a special machine. The upper end of the ceramic center rod 2 is pressed into the suction nozzle 1 position and the lower end is pressed into the oil cup 3 position without glazing. The roughness of the ceramic itself is used to ensure that a small interference fit has sufficient friction. At the same time, the thermal expansion coefficient of ceramic is lower than that of metal, and it will not loosen even if high temperature is generated during work.

[0025] The ceramic center rod 2 is a cylindrical structure with the same outer diameter. In the past, the center rods of atomizers were large for mounting the ceramic atomizing core, small for the air outlet at the upper end, and similar in appearance to a grenade. The atomizer designed in the present utility model is the first to use a purely cylindrical ceramic center rod 2 in this field. Except for the oil inlet hole, there are no protrusions or depressions. The outer diameters of the upper end and the connecting part of the suction nozzle 1 and the lower end of the oil pressure cup 3 are the same. The suction nozzle 1 that matches it is also a slight interference fit with a pure cylindrical smooth inner hole (without any rib protrusions as compensation for interference deformation), so the outer diameter size accuracy of the ceramic center rod 2 is very high. The ceramic center rod 2 is designed to be purely cylindrical to facilitate fully automatic lathe processing and one-time processing. The outer diameter of the ceramic center rod 2 is pre-processed by machine tools to ensure the accuracy of about ±0.015 mm, and the inner hole accuracy of the suction nozzle 1 is about ±0.02 mm. The outer diameter of the ceramic center rod 2 is 5 to 8 wires larger than the inner diameter of the suction nozzle. Due to the slight elasticity of the plastic, the ceramic center rod 2 can be gently pressed in. After being pressed in, the resilience of the plastic will tightly clamp the ceramic center rod 2 and connect them together.

[0026] See Figure 2 , the part of the oil cup 3 contacting the base 4 is provided with a plurality of vertical grooves 301. When the oil cup 3 and the hardware base 4 are assembled, they are also pressed in by a slight interference fit. The outer diameter of the bottom of the oil cup 3 is a few wires larger than the inner diameter of the base 4. The position where the oil cup and the base 4 contact each other is provided with a plurality of vertical grooves 301. The function of the groove 301 is to place the wire of the atomizer core. The wire diameter is about 0.15 mm and the groove depth is about 0.1 mm. Before the oil cup 3 is pressed into the hardware base, the wire of the atomizer core in the ceramic center rod 2 can be folded in advance and placed in the groove 301 set on the oil cup. Therefore, when the base 4 is pressed, the wire will not be broken and a few wires of contact will be left to form a circuit loop. If you are worried that the base 4 will fall off, the oil cup 3 and the base 4 can also be glued to reinforce the bonding. The oil cup 3 is made of PCTG plastic material, which has excellent corrosion resistance and prevents oil leakage from the oil cup.

[0027] It also includes a nozzle silicone pad 6 and an electrode silicone pad 7, and the ceramic center rod 2 passes through the nozzle silicone pad 6 and is interference-connected with the nozzle 1. It also includes an electrode 5 that passes through the electrode silicone pad 7 and is clamped with the base 4.

[0028] See Figure 3A guide hole 101 is provided at the end of the nozzle 1, and a rivet hole 102 is provided at the bottom of the guide hole 101. The diameter of the guide hole 101 is larger than the diameter of the rivet hole 102, and the ceramic center rod 2 passes through the guide hole 101 and has an interference fit with the rivet hole 102. The guide area is in front of the rivet area, and its outer diameter is slightly larger than that of the ceramic center rod, and the guide length is several millimeters. When the nozzle 1 is placed on the ceramic center rod 2, it first passes through the guide hole 101 area. The inner diameter of the plastic in this area is several threads larger than that of the ceramic center rod 2, so it can be easily put on. The gap of several threads can prevent the nozzle 1 from shaking left and right after it is put on, so that the nozzle 1 will not be pressed out of position when the whole plate is pressed after oiling.

[0029] The utility model utilizes the friction and stability of the ceramic center rod 2, combined with the plasticity of the plastic material, and adopts a slight interference fit and light riveting method to connect, which can effectively reduce the use of glue or even completely eliminate glue, thereby improving product reliability, assembly efficiency, and delivery speed.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
