Description

Technical Field

[0001] The utility model belongs to the technical field of electronic atomizers, and particularly relates to a nozzle mortise and tenon structure and a fixture of an electronic atomizer. Background Art

[0002] Ceramics are a brittle material and are widely used in electronic atomizers. When the ceramic nozzle and the ceramic center rod of the electronic atomizer are connected by a slight interference fit, an elastic plastic part is set between the two for transition. This causes the nozzle to be subjected to radial pressure from the elastic plastic part. If the wall thickness of the ceramic nozzle is thin, the nozzle may be cracked.

[0003] The second problem that the present application needs to solve is that the ceramic center column has a large length tolerance and the plastic buckle in the mouthpiece often does not fit in place, resulting in poor sealing. This problem is serious in the application of the ceramic center column in the field of atomizers. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a mortise and tenon structure for the nozzle of an electronic atomizer to solve the problem that the thin wall thickness of the ceramic nozzle may cause the nozzle to be cracked. At the same time, a fixture is provided to solve the problem that the length tolerance of the ceramic center column is too large and the plastic buckle in the nozzle is often not properly matched, resulting in poor sealing.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0029] Reference Figure 1-Figure 4The utility model provides a mortise and tenon structure of a nozzle of an electronic atomizer, comprising a ceramic center rod 1, a ceramic nozzle 2, an elastic connector 3 and an oil cup 5. The ceramic center rod 1 is inserted into the oil cup 5 made of plastic material and slightly interferes with it. The elastic connector 3 is sleeved on the end of the ceramic center rod 1. The end of the ceramic center rod 1 is provided with a chamfer to facilitate positioning and sleeve use. In this embodiment, the elastic connector 3 is made of plastic material, the ceramic nozzle 2 is sleeved on the elastic connector 3, a slot 301 is provided on the outer side of the elastic connector 3 along the circumferential direction, and an insert block 201 is provided on the inner side of the ceramic nozzle 2 along the circumferential direction. The insert block 201 can be inserted into the slot 301 so that the sides of the two are interfered in the circumferential direction. The width of the slot 301 is slightly smaller than that of the insert 201 by a few inches, so that the radial pressure exerted by the elastic connector 3 on the ceramic nozzle 2 is converted into the side extrusion force of the insert 201 and the slot 301 in the circumferential direction, so that even if the wall thickness of the ceramic nozzle 2 is made thin, there is no need to worry about it being squeezed and cracked by the elastic connector 3. Moreover, the mortise and tenon structure is used for the first time on the atomizer ceramic nozzle 2 and the elastic connector 3, and can be firmly connected without using glue, with sufficient friction, which solves the risk of plastic parts falling off due to aging of glue.

[0030] The slots 301 and the insert blocks 201 are evenly and symmetrically arranged in multiple groups along the circumferential direction, so that the force is evenly distributed and the structure is more stable. The ends of the insert blocks 201 are provided with chamfers to facilitate positioning and insertion.

[0031] A limiting ring 202 is provided inside the ceramic nozzle 2, and the inner diameter of the limiting ring 202 is smaller than the outer diameter of the elastic connecting part 3. When the elastic connecting part 3 is pressed into the ceramic nozzle 2, the limiting ring 202 limits the pressing depth of the elastic connecting part 3, thereby ensuring that the elastic connecting part 3 is in a fixed position inside the ceramic nozzle 2 after being pressed into the ceramic nozzle 2.

[0032] An annular groove 101 is provided at the end of the ceramic center rod 1, and a plurality of claws 302 are provided at the top of the elastic connector 3. The elastic connector 3 is clamped in the annular groove 101 through the plurality of claws 302 at the top, and the plurality of claws 302 are evenly arranged along the circumference of the elastic connector 3.

[0033] from Figure 1It can be seen that the function of the ceramic center rod 1 is to connect the oil cup 5 and the ceramic suction nozzle 2 to form a whole. First, the large end of the tail of the ceramic center rod 1 is inserted into the oil cup 5 and connected to the oil cup 5, and the thin end of the ceramic center rod 1 is exposed outside the oil cup 5. Here is an important detail: when assembling, the length of the section of the center rod of each atomizer exposed outside the oil cup 5 must be consistent, because when the suction nozzle is installed after the oil cup 5 is filled with oil, if the length of the section of the ceramic center rod 1 exposed is inconsistent, there will be problems: if the ceramic center rod 1 is exposed too short, the elastic connector 3 installed in the suction nozzle will not be able to get stuck on the groove of the ceramic center rod 1; if the ceramic center rod 1 is exposed too long, the suction nozzle will be loose when installed, and the sealing will be poor when shaking left and right. The ceramic center rod 1 made of ceramic material will soften and crystallize during the high-temperature sintering process. Factors such as kiln temperature or ceramic deformation will cause the ceramic to have a large tolerance. According to the tolerance range of 1%, the length tolerance of the ceramic center rod 1 with a length of about 40 mm reaches 0.4 mm, which is completely unusable in traditional structure atomizers. In the present patent, the atomizer ceramic center rod 1 is designed with a structure without any protrusions on the surface, so that there is no obstruction when it is pressed into the oil cup 5. Pressing it a little deeper or a little shallower will not affect the use. Therefore, we only need to reserve the length of the section of the ceramic center rod 1 left outside the atomizer oil cup 5, and there is no limit on the depth of the other end pressed into the oil cup 5. After the ceramic center rod 1 is pressed to a certain depth inside the oil cup 5, whether the ceramic center rod 1 is longer or shorter will not affect the length of the section exposed outside the oil cup 5. Therefore, there is no need to screen the length of the ceramic center rod 1 before use. This solves the limitation on the application of ceramic materials in the field of electronic atomizers due to large tolerances, greatly reduces the cost of using the ceramic center rod 1, and the application of the ceramic center rod 1 also solves the problem that the heavy metal content of the metal ceramic center rod 1 is easily exceeded.

[0034] Reference Figure 5 The utility model provides a jig, in which the atomizer oil cup 5 and the ceramic center rod 1 are riveted, and a gap of about 0.5 mm in height (the height is marked as h1 in the figure) is reserved on the oil cup 5. The function of this gap is to adjust the depth of the ceramic center rod 1 when it is pressed in. No matter it is pressed in a little more or a little less, it will not hit the bottom of the oil cup 5.

[0035] The ceramic center rod 1 has only three outer diameter dimensions except for the slope between the large end and the thin end: the large end, the thin end and the annular groove 101. Such a structure is convenient for improving turning efficiency and reducing material loss. If ceramic material is selected, the damage to the ceramic can be reduced, the production efficiency can be improved and the cost can be reduced. At the same time, the ceramic center rod 1 with only three application sizes effectively improves the reliability of the atomizer, because the more parameters there are, the greater the probability of problems.

[0036] The length of the ceramic center rod 1 exposed from the oil cup 5 is controlled by a special jig during assembly, including an upper jig 9 and a lower jig 10. The lower jig 10 has a small hole that can just insert the end of the ceramic center rod 1. The depth of the jig hole is the same as the number of millimeters that the ceramic center rod 1 needs to be exposed from the oil cup 5. After the thin end of the ceramic center rod 1 is inserted into the jig hole of the lower jig 10, the large end of the tail faces upward, and the oil cup 5 is put on from the large end. The upper jig 9 is placed above the oil cup 5 and starts to press down. When the oil cup 5 is pressed close to the plane of the lower jig 10, it can no longer be pressed. At this time, the oil cup 5 is taken out. The length of the ceramic center rod 1 that is higher than the oil cup 5 is exactly the depth of the hole in the lower jig 10, that is, the length that the ceramic center rod 1 needs to be higher than the oil cup 5 (the height is marked as h2 in the figure). Relying on this upper jig 9 and lower jig 10, it can be ensured that the height of the ceramic center rod 1 of each atomizer that is higher than the oil cup 5 is consistent.

[0037] During assembly, the ceramic center rod 1 is inserted into the oil cup 5 through the upper fixture 9 and the lower fixture 10 with a slight interference fit therewith. The elastic connector 3 is first pressed into the ceramic nozzle 2, and then the silicone gasket 4 and the elastic connector 3 are sequentially sleeved on the ceramic center rod 1, so that the silicone gasket 4 is clamped between the oil cup 5 and the ceramic nozzle 2. The tail of the oil cup 5 is sequentially connected with the base 6, the electrode silicone pad 7 and the electrode 8.

[0038] 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.
