Therefore, the various sequences in the specification and drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0025] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequence or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling) unless otherwise specified.

[0026] The traditional key structure is that the key column 21 and the butt joint groove 112 are sleeved, when the key 20 is installed and fixed, the glue (such as quick-drying glue) is extruded on the whole side wall of the butt joint groove 112, after the glue is extruded, the key column 21 is sleeved in the butt joint groove 112, and the adhesion and fixation of the key 20 are realized through the contact between the glue on the side wall of the butt joint groove 112 and the side wall of the key column 21. In this process, the glue is extruded in the butt joint groove 112, on the one hand, it is inconvenient to operate, on the other hand, the extruded glue is relatively more, and the problems of glue overflow and glue residue are prone to occur. In order to solve the problems of glue overflow and glue residue, a plurality of glue overflow grooves 211 are arranged on the side wall of the key column 21 which is sleeved with the butt joint groove 112, and the specific technical scheme of the key structure designed in the application is introduced as follows:

[0027] Please refer to Figures 1-5 In an embodiment of the application, a key structure is provided, comprising a bearing part 10 and a key 20. The end face of the bearing part 10 is provided with an assembly block 111, and the assembly block 111 is provided with a butt joint groove 112 away from the end face of the bearing part 10. The key 20 comprises a key column 21, the key column 21 is sleeved in the butt joint groove 112, the end face of the key column 21 facing the butt joint groove 112 is a glue applying face 215, a plurality of circumferentially spaced glue overflow grooves 211 are arranged on the outer side wall of the key column 21, the glue overflow grooves 211 are communicated with the glue applying face 215, and the glue overflow grooves 211 are used to fill glue to adhesively fix the key 20 and the bearing part 10.

[0028] By using the key structure in the above embodiment, the end face of the key column 21 facing the butt joint groove 112 is set as the glue applying face 215, which can facilitate operation, reduce the amount of glue applying, and improve the problems of glue overflow and glue residue. Moreover, a plurality of glue overflow grooves 211 which are communicated with the glue applying face 215 are arranged on the side wall of the butt joint, so that after the key column 21 is sleeved in the butt joint groove 112, the glue on the glue applying face 215 is extruded and flows to the glue overflow grooves 211, the glue is solidified at the glue overflow grooves 211, the key 20 is adhesively fixed on the bearing part 10, and the glue overflow grooves 211 can provide enough space for the glue to avoid the glue from flowing outward, thereby improving the problems of glue overflow and glue residue.

[0029] The glue overflow grooves 211 on the outer side wall of the key column 21 can be formed by arranging a plurality of convex ribs 212 on the outer side wall of the key column 21, and the glue overflow grooves 211 are formed between adjacent convex ribs 212, for example, as shown in Figure 4 , or the glue overflow grooves 211 can be directly formed by arranging a radially inward recessed structure on the outer side wall of the key column 21, for example, as shown in Figure 5 .

[0030] Please refer to Figure 4 and Figure 5The length direction of the glue overflow groove 211 is parallel to the axial direction of the key column 21, and the length of the glue overflow groove 211 is the same as or close to the axial length of the key column 21, so that more accommodation space can be provided for the glue flowing into the glue overflow groove 211, and the glue overflow and glue residue phenomenon caused by the continuous outward flow of the glue can be avoided. The length of the glue overflow groove 211 depends on the bonding strength between the key 20 and the carrier 10. For example, when the bonding strength between the key 20 and the carrier 10 is relatively low, the amount of glue extruded at the glue extrusion surface 215 can be reduced, and the length of the glue overflow groove 211 can be reduced. In addition to being parallel to the axial direction of the key column 21, the length direction of the glue overflow groove 211 can also be inclined, as long as the glue overflow groove 211 can provide a certain accommodation space for the glue between the butt joint groove 112 and the key column 21. The length and length direction of the glue overflow groove 211 are not limited in the application, and can be flexibly selected according to actual conditions.

[0031] Please refer to Figures 2-4 The end surface of the carrier 10 is provided with an assembly groove 113, and the assembly groove 113 is provided with an assembly block 111. The key 20 further comprises a key cover 22, the key column 21 is arranged in the key cover 22, and the key cover 22 is sleeved in the assembly groove 113 outside the assembly block 111.

[0032] Specifically, for example, Figure 2 and Figure 4 The assembly groove 113 is a hexagonal groove, the assembly block 111 is a hexagonal block, a hexagonal annular groove is formed between the inner wall of the assembly groove 113 and the outer wall of the assembly block 111, and the shape of the key cover 22 is matched with the shape of the hexagonal annular groove. Correspondingly, the shape of the key column 21 is also matched with the shape of the butt joint groove 112. The shape mentioned here is only an example and should not be understood as a limitation of the application. The specific shape can be flexibly selected according to actual needs.

[0033] As shown in Figure 3 After the key 20 is sleeved on the carrier 10, the two sides of the key cover 22 are in contact with the inner wall of the assembly groove 113 and the outer wall of the assembly block 111, respectively, and the side wall of the key column 21 without the glue overflow groove 211 is in contact with the groove wall of the butt joint groove 112. In order to facilitate the assembly of the key 20, the end of the key column 21 and the key cover 22 facing the carrier 10 can also be provided with a guide surface to facilitate the rapid installation of the key 20.

[0034] Please refer to Figure 3 and Figure 4The bottom of the key cover 22 is provided with a support portion 221, the support portion 221 is in contact with the end face of the assembly block 111, and the support portion 221 forms a residual glue groove between the bottom of the key cover 22 and the end face of the assembly block 111. By forming the residual glue groove between the bottom of the key cover 22 and the end face of the assembly block 111 through the support portion 221, a further guarantee structure is provided. When the glue in the overflow groove is too much, a certain accommodation space is provided through the residual glue groove, so that the glue flowing to the residual glue groove can be accommodated and solidified, and the glue overflowing from the overflow groove can be prevented from continuing to flow outward.

[0035] The support portion 221 in the bottom of the key cover 22 can be strip-shaped, block-shaped or ring-shaped, etc. For example, as shown in FIG. 8, the support portion 221 is strip-shaped, a plurality of circumferentially and equally spaced support portions 221 are arranged in the bottom of the key cover 22, one end of the strip-shaped support portion 221 is connected with the assembly block 111, the other end of the support portion 221 is connected with the side wall of the key cover 22, and the residual glue groove is formed by the adjacent support portion 221, the inner wall of the assembly groove 113, the outer wall of the assembly block 111 and the bottom of the key cover 22. Figure 4 For another example, the support portion 221 is ring-shaped, and the residual glue groove is formed by the inner wall of the support portion 221, the outer wall of the assembly block 111 and the bottom of the key cover 22. At this time, the inner diameter of the ring-shaped support portion 221 is smaller than the outer diameter of the assembly block 111, so that a relatively closed residual glue groove can be formed after the support portion 221 and the end face of the assembly block 111 are in contact or abutment. Even if the glue at the overflow glue groove 211 flows to the residual glue groove and has not yet solidified, it cannot continue to flow outward, which better prevents the overflow of glue and the residual glue phenomenon.

[0036] Please refer to Figure 4 Preferably, the inner wall of the key cover 22 is provided with a plurality of circumferentially and equally spaced pre-tightening strips 222, and the pre-tightening strips 222 abut against the outer side wall of the assembly block 111. By abutting and pressing the pre-tightening strips 222 and the outer side wall of the assembly block 111, the fixing strength of the key 20 on the carrier 10 can be further enhanced on the basis of the glue fixing between the key 20 and the carrier 10. In addition, the inner wall of the key cover 22 abuts between the outer wall of the assembly block 111, which not only guarantees the connection strength, but also reduces the contact area between the key cover 22 and the assembly block 111, reduces the resistance when the key 20 is sleeved, and facilitates the quick installation of the key 20. In addition, a gap space is also formed between the adjacent pre-tightening strips 222, and if the glue at the residual glue groove continues to flow outward, it can also be accommodated through the gap space formed between the pre-tightening strips 222 to prevent the glue from flowing outward.

[0037] Please refer to Figure 4In order to quickly sleeve the key 20 on the carrier 10, the convex rib 212 on the side wall of the key column 21 away from the bottom of the key cover 22 can be provided with a first guide surface 213, and the pre-tightening strip 222 away from the bottom of the key cover 22 can be provided with a second guide surface 223. Through the guiding effect of the first guide surface 213 and the second guide surface 223, the key 20 can be quickly sleeved and fixed on the carrier 10.

[0038] Please refer to Figures 3-5 The end face of the key column 21 facing the butt joint groove 112 is provided with a groove 214. Through the structure of the groove 214, on the one hand, the key column 21 is convenient to process, and on the other hand, there is also a certain space in the groove 214, and the glue at the glueing surface 215 can also flow into the groove 214, increasing the bonding area between the key 20 and the carrier 10, which helps to ensure the installation strength of the key 20 on the carrier 10, avoids the phenomenon of shaking and loosening of the key 20, and ensures the use effect or use experience of the key 20.

[0039] Specifically, the gap between the groove bottom of the overflow groove 211 and the side wall of the butt joint groove 112 is 0.03mm-0.07mm. Under this interval range, it is convenient to ensure that the glue can fill the interval space at the overflow groove 211, and then ensure the bonding strength between the key 20 and the carrier 10.

[0040] Please refer to Figure 5 More preferably, the glueing surface 215 is provided with a limiting piece 216, and the length of the limiting piece 216 protruding axially relative to the glueing surface 215 is 0.03mm-0.07mm. The limiting piece 216 is used to limit the amount of glue on the glueing surface 215. For example, when the glue is extruded to the glueing surface 215, when the thickness of the glue on the glueing surface 215 is consistent with the axial length of the limiting piece 216, it means that the amount of glue on the glueing surface 215 reaches the required amount of glue. Through the limiting piece 216, it is convenient to ensure the consistency when the operator or the machine extrudes the glue to the glueing surface 215, and to ensure the consistency of the installation of the key 20. The groove bottom of the butt joint groove 112 is provided with a limiting groove (not shown), and the limiting piece 216 and the limiting groove are concave-convex matched. After the glueing surface 215 extrudes the required amount of glue, the key 20 and the butt joint groove 112 or the assembly groove 113 are aligned and sleeved, the key 20 is pressed, the limiting piece 216 and the limiting groove are concave-convex matched, the glueing surface 215 and the groove bottom of the butt joint groove 112 are close to each other, the glue at the glueing surface 215 is extruded, the glue at the glueing surface 215 flows to the overflow groove 211 side and solidifies, and the bonding and fixing between the key 20 and the carrier 10 are realized. The limiting piece 216 can be a limiting ring or a plurality of limiting blocks, and the shape and number of the limiting groove are one-to-one corresponding to the limiting piece 216.

[0041] The interval between the cover bottom of the key cover 22 and the end face of the assembly block 111 at the residual glue groove is 0.03mm-0.07mm, that is, the thickness of the residual glue groove in the axial direction is 0.03mm-0.07mm, so as to further provide sufficient accommodation space for the glue and avoid the glue flowing to the outside. Based on the amount of glue on the key structure and the flow path, the interval space at the glue applying surface 215, the interval space at the overflow glue groove 211 and the interval space at the residual glue groove gradually decrease in turn, for example, the interval space at the glue applying surface 215 is 0.06mm, the interval space at the overflow glue groove 211 is 0.05mm, and the interval space at the residual glue groove is 0.03mm.

[0042] When the key structure in the above embodiment is installed, the quick-drying glue is applied on the glue applying surface 215, then the key 20 and the carrier 10 are sleeved, and then the key 20 is pressed. Since the glue has fluidity, the excess quick-drying glue can flow into the overflow glue groove 211 of the key column 21, when the overflow glue groove 211 is filled with the quick-drying glue, the key column 21 and the side wall of the butt joint groove 112 of the carrier 10 are adhered. If there is still excess quick-drying glue, it can flow into the residual glue groove, and if there is still excess quick-drying glue, it can flow into the gap or interval space at the pre-tightening strip 222.

[0043] The key structure provides the glue applying surface 215, which can facilitate the application or extrusion of the glue and reduce the amount of glue. The overflow glue groove 211 and the residual glue groove effectively prevent the glue from flowing to the outside, thereby solving the problems of glue overflow and residual glue. The pre-tightening strip 222 on the side wall of the key cover 22 and the overflow glue groove 211 can effectively ensure the assembly strength of the key 20 on the carrier 10. The designed key structure is simple, low in cost and convenient to assemble.

[0044] In another embodiment of the present application, a nebulizer is provided, which comprises a shell (not shown) and a key structure, and the key structure is the key structure in the above embodiment. The shell is provided with a key hole, the carrier 10 is movably arranged in the shell, the key 20 is arranged in the key hole, the carrier 10 is provided with an air inlet structure 114, and the key 20 is used to drive the carrier 10 to move to change the air inlet amount of the air inlet structure 114.

[0045] Specifically, please refer to Figure 2 The carrier 10 is in a plate structure, and the carrier 10 comprises a main body plate 11 and a side plate 12 which are integrally connected, and the side plates 12 are symmetrically fixed on both sides of the main body plate 11. The main body plate 11 is provided with an assembly groove 113 and an air inlet structure 114. The main body plate 11 is movably arranged in the shell through the side plates 12 on both sides, the air inlet structure 114 is a plurality of air inlet holes provided on the main body plate 11, the position of the carrier 10 is changed by the key 20, so as to change the number of exposed air inlet holes, thereby adjusting the air inlet amount, and at this time, the designed carrier 10 is similar to an air adjusting plate.

[0046] Please refer toFigure 2 The bottom outer side end surface of the key cover 22 is provided with an operation part 224 for facilitating the user to push the key 20. Figure 2 As shown in FIG. 4, the operation part 224 is a plurality of concave strip-shaped grooves, or the operation part 224 is a plurality of densely distributed convex points, etc.

[0047] In other embodiments, the carrier 10 can also be rotatably arranged in the shell, and the air intake amount is changed by rotating the carrier 10 through the key 20. In addition to being a plurality of holes, the air intake structure 114 can also be a strip-shaped air intake port, and the air intake amount is adjusted by adjusting the size of the exposed air intake port.

[0048] With the traditional key structure, the glue inside is prone to flow to the outside, such as flowing between the shell and the key 20, so the existing key structure has the problems of glue overflow and residue, and the key 20 is stuck. When the key 20 is stuck, it cannot be installed, and it cannot be used subsequently.

[0049] However, by using the key structure in the above embodiments designed by the present application, through the overflow groove 211, the glue residue groove, and the gap or spacing space at the pre-tightening strip 222, the glue can be effectively prevented from flowing to the outside, especially to the shell and the key 20, effectively solving the problems of glue overflow, residue, and key 20 stuck.

[0050] In another embodiment of the present application, an atomization device is provided, which comprises an atomizer, an electric core and a circuit board. The atomizer is the atomizer in the above embodiments. The atomizer comprises an atomizing core, and the heating element in the atomizing core and the electric core are electrically connected with the circuit board respectively. The electric core is used to provide electric energy for the heating element, and the circuit board is used to control the working state of the heating element. Since the atomization device comprises the atomizer comprising the key structure in the above embodiments, it also has the advantages of the key structure in the above embodiments, which will not be described in detail here.

[0051] The key structure is a common structure that facilitates user control of products. It can be understood that, in addition to being applied to the above-mentioned atomizer and atomization device, it can also be applied to other products, such as interphones, electric toothbrushes, watches, etc. The specific application scenarios of the key structure are not specifically limited by the present application, and can be flexibly applied according to actual needs. Similarly, other products using the key structure in the above embodiments designed by the present application also have the advantages or beneficial effects of the key structure in the above embodiments.
