Figure 1 The gap X shown is shown. Products with gap X have a higher risk of oil leakage. Utility Model Content

[0003] The main purpose of the utility model is to provide an assembly jig for an electronic atomizer, which can eliminate the assembly gap between the glass fiber tube and the oil-conducting cotton and improve the product assembly quality.

[0004] To achieve the above-mentioned object, the present application provides an assembly jig for an electronic atomizer, wherein the electronic atomizer comprises an oil storage cotton assembled in an oil cup and an oil guide cotton and a glass fiber tube installed in the oil storage cotton in sequence. The assembly jig comprises:

[0005] A first fixture, used for carrying the electronic atomizer;

[0006] a second jig having a first end face and a second end face disposed toward the first jig, wherein after the first jig is clamped, the first end face abuts against the oil storage cotton, and the second end face abuts against the glass fiber tube;

[0007] The spring continuously supports the second end surface.

[0008] Compared with the prior art, after the first jig and the second jig are clamped together, the second end face pushes the fiberglass tube toward the oil-conducting cotton under the support of the spring until the fiberglass tube can no longer move under the support of the spring, or the end face of the oil-conducting cotton abuts against the first end face. It is determined that the fiberglass tube abuts against the oil-conducting cotton, and the gap between the fiberglass tube and the oil-conducting cotton disappears.

[0009] In some embodiments, the second fixture includes a first base, a second base, and a movable part. The first base is provided with a step hole. The second base, the movable part, and the spring are sequentially arranged in the step hole. The second base supports the first end face, and the second base is provided with a through hole connected to the step hole. The spring supports the movable part to be partially inserted into the through hole, and the movable part supports the second end face on the side close to the first end face.

[0010] In some embodiments, the large diameter hole of the step hole is located on a side close to the first fixture, at least part of the second base is installed in the large diameter hole, and the inner diameter of the through hole is smaller than the inner diameter of the small diameter hole of the step hole.

[0011] In some embodiments, the second fixture further includes a support pin having an external thread, an end of the step hole close to the small diameter hole is provided with an internal thread, the support pin is threadedly connected to the step hole, and the spring abuts against the support pin.

[0013] In some embodiments, the first base further includes a third end surface on the same side as the first end surface, and the third end surface abuts against the end surface of the oil cup after the first fixture and the second fixture are clamped together.

[0014] In some embodiments, the movable part is convex-shaped, the end with a larger diameter of the movable part is located in the step hole, and the end with a smaller diameter of the movable part is located in the through hole under the support of the spring to support the second end surface.

[0015] In some embodiments, the distance between the first end surface and the second end surface is equal to the distance between the end surface of the oil storage cotton and the end surface of the oil cup.

[0016] Compared with the prior art, the present invention has the following advantages: during the clamping process of the first jig and the second jig, as the first jig and the second jig approach each other, the second end face abuts against the glass fiber tube, and the second end face pushes the glass fiber tube to move in the mounting hole of the oil storage cotton in the direction of the oil guide cotton under the support of the spring, gradually narrowing the gap between the glass fiber tube and the oil guide cotton. At the same time, when the first end face abuts against the end face of the oil storage cotton, the electronic atomizer maintains a relatively fixed position with the second jig, the glass fiber tube is subjected to movement resistance, and it is determined that the glass fiber tube abuts against the oil guide cotton. It can be determined that the assembly gap between the glass fiber tube and the oil guide cotton is close to zero, thereby improving the product assembly quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present application belongs. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] In the description of this application, unless otherwise specified or defined, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components, unless otherwise specified or defined. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0034] Electronic atomizers can be used in different fields, including but not limited to those used in industries such as medical atomization, cosmetic atomization, and cigarette replacement. They are mainly used to atomize an aerosol-generating matrix to form an aerosol. The aerosol-generating matrix can be a liquid matrix of a medicinal solution, a nutrient solution, etc. Taking the electronic atomizer that can replace cigarettes as an example, the electronic atomizer includes a detachable power supply component and an atomizer component. The atomizer component includes an oil cup 10, oil storage cotton 11, a heating element 15, an atomizer tube 13, oil guide cotton 14 and a glass fiber tube 12. The oil cup 10 has two opposite ends, one of which is sealed by a silicone base 16. The oil storage cotton 11 is provided with a mounting hole that passes through the oil storage cotton 11. The oil storage cotton 11 is arranged in the oil cup 10. The atomizer tube 13 is arranged in the mounting hole at one end close to the silicone base 16. The heating element 15 is fixed in the atomizer tube 13. An oil inlet hole is provided on the side of the atomizer tube 13. The oil guide cotton 14 is at least partially located in the oil inlet hole. The glass fiber tube 12 is inserted into the mounting hole from the end of the oil cup 10 away from the heating element. Figure 1 As shown, before using the assembly jig of the present application, the glass fiber tube 12 is at least partially pre-inserted into the mounting hole, and there is a gap X between the glass fiber tube 12 and the oil-conducting cotton 14 due to dimensional tolerance.

[0035] The present application provides an assembly jig for an electronic atomizer 1, such as Figure 1-Figure 3As shown, the assembly jig has a spring 23 and a first jig and a second jig 2 arranged opposite to each other, wherein the first jig is used to support the electronic atomizer 1, and has a first end face 21 and a second end face 22 arranged toward the first jig, and the spring 23 continuously supports the second end face 22; after the first jig is clamped, the first end face 21 abuts against the oil storage cotton 11, and the second end face 22 abuts against the glass fiber tube 12.

[0036] Specifically, refer to Figure 5-8 As shown, after the first fixture and the second fixture 2 are clamped together, the second end face 22, supported by the spring 23, pushes the glass fiber tube 12 toward the oil-conducting cotton 14. The glass fiber tube 12 cannot move further under the support of the spring 23, or the oil-reservoir cotton 11 abuts the first end face 21. This can be considered as the glass fiber tube 12 abutting the oil-reservoir cotton 14, and the gap between the glass fiber tube 12 and the oil-reservoir cotton 14 disappears. In the case where the oil-reservoir cotton 11 and the oil cup 10 are already assembled, the end face of the glass fiber tube 12 should have a relatively fixed distance from the end face of the oil-reservoir cotton 11 after assembly. Therefore, after the oil-reservoir cotton 11 abuts the first end face 21, it can be considered as the glass fiber tube 12 abutting the oil-reservoir cotton 14. The distance from the end face of the glass fiber tube 12 to the end face of the oil-reservoir cotton 11 is the distance between the first end face 21 and the second end face 22.

[0037] Specifically, the present application provides an assembly jig that can be used for assembling an electronic atomizer 1. The assembly jig includes a spring 23 and a first jig and a second jig 2 that can move relative to each other and clamp together, wherein the first jig is used to clamp the electronic atomizer 1 where the gap between the fiberglass tube 12 and the oil-conducting cotton 14 is to be eliminated.

[0038] It is understandable that there are multiple ways for the first fixture to clamp and fix the electronic atomizer 1, including but not limited to through a groove or a clamping arm. In some embodiments, the inner diameter of the groove is adapted to the outer diameter of the oil cup 10, and a hole can be opened at the bottom of the groove to avoid connecting the electrodes of the heating element 15. During assembly, the end of the oil cup 10 to be assembled close to the heating element 15 is placed in the groove, so that part of the oil cup 10 or the glass fiber tube 12 is exposed in the groove. After the first fixture and the second fixture 2 are clamped together, the oil storage cotton 11 in the oil cup 10 abuts the first end face 21, and the glass fiber tube 12 abuts the second end face 22. At the same time, the spring 23 pushes the second end face 22 under its own elastic tension to squeeze the glass fiber tube 12 in the direction of the oil guide cotton 14 until the glass fiber tube 12 encounters movement resistance or the oil storage cotton 11 abuts the first end face 21, and it is determined that the glass fiber tube 12 has abutted the oil storage cotton 11.

[0039] like Figure 4As shown, the second fixture 2 includes a first base 20, a second base 210, and a movable part 220. A step hole is provided on the end face of the first base 20 close to the first fixture, and the step hole can pass through the first base 20. One end of the diameter hole of the step hole is close to the first fixture; the second base 210 has a base and a boss 211 located on the base. The base is installed in the large diameter hole 200. The first boss 211 protrudes from the first base 20, and the second base 210 has an outer diameter less than or equal to the inner diameter of the oil cup 10. The end face of the second base 210 close to the first fixture is the first end face 21. A through hole connected to the step hole is provided on the second base 210. The movable part 220 and the spring 23 are sequentially arranged in the step hole between the first base 20 and the second base 210 from one end of the large diameter hole 200. The spring 23 supports the movable part 220 to be partially inserted into the through hole. The end face of the movable part 220 close to the first end face 21 is the second end face 22.

[0040] In some embodiments, the inner diameter of the through-hole is smaller than that of the small-diameter hole 201, resulting in a convex inner wall formed at the connection between the stepped hole and the through-hole. The movable member 220 is restrained by the inner wall to prevent it from detaching from the fixture after resistance to movement disappears. It is understood that a receiving cavity is formed between the first base 20 and the second base 210, and the second base 210 has a through-hole connected to the receiving cavity. The movable member 220 and spring 23 are disposed within the receiving cavity, and the movable member 220 is partially inserted into the through-hole to contact the fiberglass tube 12.

[0041] In some embodiments, as Figure 4 As shown, the movable part 220 is roughly convex in shape, with the large-diameter end of the movable part 220 located in the step hole, and the small-diameter end of the movable part 220 extends into the through hole under the support of the spring 23 to support the second end face 22, and the step on the movable part 220 abuts against the protruding inner wall at the connection point between the above-mentioned step hole and the through hole.

[0042] In some embodiments, the second fixture 2 further includes a support pin 24 having an external thread, such as Figure 4 As shown, one end of the small-diameter hole 201 is provided with an internal thread, the support pin 24 is threadedly connected to the stepped hole, and one end of the spring 23 abuts against the support pin 24. During the assembly process, the operator can move the support pin 24 to compress the spring 23 according to actual conditions, so that the spring 23 can provide a greater thrust to the movable member 220 to push the glass fiber tube 12 to move.

[0043] In some embodiments, an end of the support pin 24 away from the spring 23 is provided with an open groove, and the open groove includes but is not limited to common groove shapes such as a straight shape, a cross shape, a star shape, and a hexagonal shape.

[0044] In some embodiments, the first base 20 further includes a third end face on the same side as the first end face 21. After the first jig and the second jig 2 are clamped together, the third end face abuts the end face of the oil cup 10 to confirm that the glass fiber tube 12 has been inserted into the mounting hole. The third end face is on the same side as the first end face 21, and there is a distance difference between the first end face 21 and the third end face. This distance difference is designed based on the distance between the end face of the oil-storing cotton 11 and the end face of the oil cup 10. When the end face of the oil cup 10 contacts the third end face, the other end face of the oil-storing cotton 11 abuts the other end of the oil cup 10. That is, after the first jig and the second jig 2 are clamped together, when the end face of the oil-storing cotton 11 and the end face of the oil cup 10 are in relative position, the glass fiber tube 12 abuts the oil-conducting cotton 14.

[0045] The above description is only part or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
