Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] In the description of the embodiments of the present invention, it should be understood that the directions or positional relationships indicated by “up”, “down”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside”, etc., are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] In order to more clearly illustrate the technical solution of the present invention, a preferred embodiment is provided below. Figure 1 to Figure 4 , a positioning fixture, comprising a fixture body 1, wherein:

[0028] A sponge placement groove 2 is provided on the top of the jig body 1; a press-in groove 3 is also provided on the top of the jig body 1, and the press-in groove 3 is opened to the bottom of the sponge placement groove 2, and the press-in groove 3 is located in the middle of the sponge placement groove 2; the jig body 1 is provided with first sliding grooves 4 on both sides of the sponge placement groove 2, and a slider 5 is slidably connected in the first sliding groove 4, and a U-shaped groove 6 is provided on the top of the slider 5 at a position corresponding to the press-in groove 3; a first spring 7 is provided in the first sliding groove 4, and the bottom of the first spring 7 is fixedly connected to the inner wall of the first sliding groove 4, and the top of the first spring 7 is fixedly connected to the slider 5, and when the first spring 7 is not subjected to external force, the U-shaped groove is located above the press-in groove 3.

[0029] The working process of a positioning fixture involved in the utility model is as follows: the sponge is placed in the sponge placement groove 2 through an externally arranged feeding device, and then the heating wire is placed above the sponge, and then the cotton-wrapped rod is fed into the U-shaped groove through an external device. While feeding, the device drives both sides of the cotton-wrapped rod to press downward. Under the pressure of the cotton-wrapped rod, the sponge and the heating wire are pressed into the pressing groove 3. Affected by the wall surface of the pressing groove 3, the sponge and the heating wire are wrapped around the outside of the cotton-wrapped rod. The design of the sponge placement groove 2 and the U-shaped groove both improves the accuracy of the position of the internal components of the atomizer core, thereby improving the yield rate of the assembled atomizer core, and because there is no need to adjust the position of components such as the heating wire and sponge, the production efficiency is improved.

[0030] It should be noted that, since the cotton-wrapped rod is loaded and pressed down by external equipment, the slider 5 is slidably connected, and the first spring 7 is arranged at the bottom thereof, so that the equipment can prevent the cotton-wrapped rod from excessively moving downward, that is, the slider 5 is pressed downward when the cotton-wrapped rod moves downward, thereby ensuring that the cotton-wrapped rod completely presses the sponge into the pressing groove 3 while avoiding collision between the cotton-wrapped rod and the jig body 1 to cause deformation or breakage.

[0031] As a preferred solution of this embodiment, the jig body 1 is provided with a second slide groove 8 downwardly in the middle of the sponge placement groove 2, and a support block 9 is slidably connected in the second slide groove 8, and the top of the support block 9 extends into the press-in groove 3; a receiving groove 10 connected to the second slide groove 8 is provided below the second slide groove 8, and a second spring 11 is provided in the receiving groove 10, and the top of the second spring 11 is in contact with the support block 9. It should be noted that after the cotton-wrapped rod presses the sponge and the heating wire into the press-in groove 3, the first spring 7 will drive the slider 5 to slide upward, and at this time, the cotton-wrapped rod will move upward, and a gap may be generated between the sponge and the cotton-wrapped rod, affecting the product quality. Therefore, in this embodiment, the design of the support block 9 is adopted, and under the action of the second spring 11, the support block 9 lifts the sponge to touch the cotton-wrapped rod, so as to ensure the product quality.

[0032] Furthermore, in the present embodiment, the fixture body 1 is composed of a base plate 12 and a main body block 13 connected to each other; the first slide groove 4 and the second slide groove 8 are respectively composed of a first groove opened on the top of the base plate 12 and a hole opened on the main body block 13, so that the slider 5, the support block 9, the first spring 7 and the second spring 11 are easily installed.

[0033] Furthermore, a limiting groove 14 is provided at the bottom of the main block 13, and limiting blocks 15 are extended from both sides of the support block 9 and the slider 5. The limiting blocks 15 are arranged in the limiting groove 14 to limit the upward range of the support block 9 and the slider 5.

[0034] As a preferred solution of this embodiment, the slider 5 is provided with first guiding inclined surfaces 16 on both sides of the top of the U-shaped groove. The first guiding inclined surfaces 16 are used to ensure that the cotton-wrapped stick can be normally introduced into the U-shaped groove when input.

[0035] As a preferred solution of this embodiment, the slider 5 is provided with a positioning groove 17 on the side of the first guide inclined surface 16 away from the U-shaped groove. Connecting feet are provided on both sides of the heating wire, and the positioning grooves 17 on both sides of the U-shaped groove are used to position the connecting feet, that is, to position the heating wire, so as to ensure that the heating wire is accurately positioned inside the assembled atomizer core.

[0036] As a preferred solution of this embodiment, the top of the slider 5 is provided with a second guiding inclined surface 18 on the side of the positioning groove 17 away from the U-shaped groove. The second guiding inclined surface 18 is used to ensure that the connecting pin of the heating wire can be normally introduced into the positioning groove 17 when input.

[0037] As a preferred solution of this embodiment, two top plates 19 are detachably mounted on the top of the fixture body 1, and the sponge placement slot 2 is composed of through holes opened on the two top plates 19. Different atomizer core sponges have different sizes, so the size of the sponge placement slot 2 can be changed by replacing the top plate 19, so that the positioning fixture has universality.

[0038] As a preferred solution of this embodiment, a third guiding inclined surface 20 is provided on the top of the top plate 19 outside the sponge placement groove 2. The second guiding inclined surface 18 is used to ensure that the sponge can be normally introduced into the sponge placement groove 2 when input.

[0039] As a preferred solution of this embodiment, a plurality of mounting holes 21 are provided on the fixture body 1 .

[0040] The positioning fixture involved in the utility model solves the problem that the manual assembly of the atomizer core of the existing electronic cigarette not only easily leads to inaccurate installation positions of the components in the atomizer core, resulting in low product yield, but also low assembly efficiency through reasonable structural settings.

[0041] The above description is only a preferred embodiment of the present invention, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
