Description

Technical Field

[0001] The utility model belongs to the technical field of electronic atomizers, and particularly relates to a connection structure of a ceramic central column of an atomizer. Background Art

[0002] The size of the ceramic center column with buckles from the top of the buckle to the bottom of the oil cup is required to be very precise, generally requiring a deviation of ±0.1mm. If this size is too large, the two buckles will be loose when the nozzle is covered, and if this size is too small, the buckles will not be able to buckle when the nozzle is covered or the buckles will be too tight to deform the silicone. Therefore, the length deviation of the ceramic center column with buckles is generally required to be ±0.1mm. The deviation exceeds ±0.1mm, which will affect the sealing and cause the risk of oil leakage. However, due to the limitation that the slight jump caused by the shrinkage rate of ceramic products during high-temperature sintering will cause a large deviation in length, and the superposition of the two factors of curvature changes makes it difficult for ceramic columns to achieve a length dimension deviation within the range of ±0.1mm. Therefore, the ceramic center column can only be selected before use, and those that exceed the length deviation cannot be used, resulting in a decrease in product yield and an increase in cost. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide a connection structure of the ceramic center column of an atomizer to address the deficiencies of the prior art, solve the influence of the length size error of the ceramic center column on the buckle position, improve the sealing of the atomizer and the yield rate of the ceramic center column, and reduce production costs.

[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.

[0022] In the description of the present utility model, it should be noted that, unless otherwise specified, "multiple" means two or more; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[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. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0024] Reference Figure 1-Figure 3 The connection structure of the atomizer ceramic center column provided by the utility model comprises a ceramic center column 1, an oil cup 2, an annular holder 3 and a suction nozzle 4. The ceramic center column 1 is inserted into the oil cup 2 and has an interference fit with the oil cup 2. Figure 2 A ring-shaped groove 101 is provided on the top of the outer side surface of the ceramic center column 1. The ring-shaped holder 3 is inserted into the suction nozzle 4 and is rotatably connected thereto. The suction nozzle 4 can rotate. If the suction nozzle 4 is in the wrong direction, the angle can be adjusted by rotation. The ceramic center column 1 can pass through the inner ring of the ring-shaped holder 3 so that the ring-shaped holder 3 is stuck in the ring-shaped groove 101. The top of the ceramic center column 1 is a conical structure, which facilitates the ceramic center column 1 to pass through the inner ring of the ring-shaped holder 3.

[0025] Since the ceramic center column 1 is plugged into the oil cup 2, the length of the exposed portion of the ceramic center column 1 is adjusted to meet the accuracy of the dimension from the top snap-in position of the ceramic center column 1 to the bottom of the oil cup 2, thereby effectively solving the effect of the length error of the ceramic center column 1 on the snap-in of the annular holder 3, thereby ensuring the sealing of the atomizer.

[0026] It also includes a nozzle silicone pad 5, which is sleeved on the ceramic center column 1 so that the nozzle silicone pad 5 abuts against the bottom of the annular holder 3 to play a role in connection and sealing.

[0027] The annular holder 3 is made of plastic material, which has good toughness and can withstand large deformation impact. Figure 3 Four claws 301 are arranged on the top of the annular holder 3, and the four claws 301 are evenly arranged along the circumference of the annular holder 3. The annular holder 3 is clamped in the annular groove 101 through the four claws 301. When the suction nozzle 4 is pressed down and sleeved on the annular holder 3 and released, the top plane of the claws 301 is pressed against the top of the annular groove 101 under the elastic action of the plastic. At this time, the size from the top of the claws 301 on the annular holder 3 to the bottom of the oil cup 2 is fixed, thereby ensuring the sealing of the atomizer.

[0028] The ceramic center column 1 is a cylindrical structure. The ceramic center column 1 is pre-grinded to the required size. The deviation value of the outer diameter of the ceramic center column 1 is ±0.015mm, so that the depth can be fine-tuned when pressing into the oil cup 2, thereby ensuring that there will be no leakage at the connection.

[0029] The outer diameter of the ceramic center column 1 of the utility model is ground, and the accuracy reaches the requirement of light riveting into the oil cup 2, and the length from the buckle position on the ceramic center column 1 to the bottom of the oil cup is controlled by the depth of riveting into the oil cup 2, which effectively solves the influence of the large length error of the ceramic center column 1 on the sealing performance. No matter how long the ceramic center column 1 is, when the ceramic center column 1 is pressed into the oil cup 2, a limited length fixture can be made so that the ceramic center column 1 is pressed to the required depth and is supported by the fixture and cannot be pressed down. In this way, the length from the buckle position on the ceramic center column 1 to the bottom of the oil cup is uniform, and the error can be controlled within ±0.1mm. The ceramic center column 1 does not need to be selected, thereby improving the yield rate of the ceramic center column 2 and reducing the production cost.

[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.
